Breaking down the Riders and Redblacks
    What can the Saskatchewan Roughriders and Ottawa Redblacks do for an encore?
 The CFL teams produced a pair of down-to-the-wire  games in the regular season, with each squad winning by a single point  on the road.
 The stakes are higher now with Riders and Redblacks  to meet Sunday in Ottawa in the East Division semi-final. The winner  advances to the East final on Nov. 19 against the host Toronto  Argonauts.
Leading up to Sunday’s playoff opener (noon CST), here’s a position-by-position breakdown of the Riders and Redblacks:
HEAD COACHES
  Sunday’s semi-final features the victorious head  coaches from the 2015 and 2016 Grey Cup games. Chris Jones, now  Saskatchewan’s head coach, guided the Edmonton Eskimos to a 26-20 win  over the Rick Campbell-coached Redblacks in the 2015 Grey Cup game.  Campbell led the Redblacks to a 39-33 overtime win over the Calgary  Stampeders in the 2016 championship game.
The similarities extend to 2017. Jones and Campbell both helped their  teams rebound from slow starts and earn berths in the East Division  semifinal. Campbell is a three-time winner of the Grey Cup. Jones has  reached the playoffs in 15 of his 16 seasons in the CFL and won the Grey  Cup four times. Jones and Campbell both have one Grey Cup victory as a  head coach. Jones gives Saskatchewan the edge simply because he is also  at the controls of one of the league’s better defences. 
Advantage: Saskatchewan.
QUARTERBACKS
  The Riders will continue with Kevin Glenn starting at  quarterback and Brandon Bridge coming off the bench if necessary.  Bridge provides a change of pace, but lacks playoff experience. Glenn,  by contrast, has started 11 playoff games over his 17-year career.  Whether he’s around to finish Sunday’s game remains to be determined.
 Ottawa’s Trevor Harris has been among the league’s  hottest quarterbacks since returning from a shoulder injury. He has 955  passing yards and seven touchdown passes in his last three games.  Sunday’s start will be his first in the playoffs, but the six-year  veteran is ready to step up. 
Advantage: Ottawa.
RECEIVERS
  Duron Carter, Naaman Roosevelt and Bakari Grant each  surpassed 1,000 receiving yards and helped the Riders lead the CFL in  aerial touchdowns (35). Carter has been at his best against the  Redblacks, with 16 receptions for 320 yards in two games.
 The loss of slotback Brad Sinopoli to a season-ending  shoulder injury was a blow to the Redblacks. Greg Ellingson remains  their best receiver, with a team-leading 1,459 receiving yards and 12  touchdown catches. Diontae Spencer finished with 922 receiving yards and  seven touchdowns. The Riders get the advantage due to the one-two punch  of Carter and Roosevelt and the overall depth. 
Advantage: Saskatchewan.
RUNNING BACKS
  Jones said Friday that he will start the healthiest  players in Ottawa. That would seem to open the door for Marcus Thigpen  to see action for the second consecutive game. The Riders’ other  American tailbacks, Cameron Marshall and Trent Richardson, have battled  injuries. With ratio considerations in mind, national Kienan LaFrance —  who helped Ottawa win the Grey Cup last year — could also be a factor.
 Ottawa’s William Powell was dominant in the Riders’  18-17 win on Sept. 29, rushing for 187 yards. The Riders limited Powell  to 10 carries for 58 yards in Ottawa’s 33-32 win at Mosaic Stadium on  Oct. 13. That was largely due to Ottawa falling behind early and having  to throw the ball. Powell gives Ottawa the edge. 
Advantage: Ottawa.
OFFENSIVE LINE
  The Riders will be without Brendon LaBatte, who is  sidelined with an injury to his left leg. LaBatte started 18  regular-season games and split time between guard and centre. Derek  Dennis, who began the season at left tackle, is expected to start at  left guard. It’s only one position switch, but the Riders will be hard  pressed to replace LaBatte’s leadership.
 Ottawa’s offensive line has steadily improved since  allowing a league-high 30 sacks over its first 12 games. Ottawa has  allowed only three sacks in its last six contests. The possible return  of tackle SirVincent Rogers, the CFL’s most outstanding offensive  lineman in 2015, from injury makes the offensive line even stronger. 
Advantage: Ottawa.
DEFENSIVE LINE
  Defensive end Willie Jefferson led the Riders with  eight sacks and paced the CFL with 37 quarterback pressures. He can  disrupt an offence with his speed, athleticism and at, 6-foot-6, size.
 Ottawa doesn’t have a disruptive force like  Jefferson, but can still bring pressure. Ottawa was fourth in the CFL  with 110 quarterback pressures, four more than the Riders. Jefferson can  influence a game by himself and his presence tips the scales. 
Advantage: Saskatchewan.
LINEBACKERS
  Middle linebacker Henoc Muamba led the Riders with 82  defensive tackles and added two interceptions. Injuries have  contributed to changes among the outside linebackers, but Derrick  Moncrief and Jeff Knox Jr. have filled in nicely.
 Taylor Reed, Ottawa’s middle linebacker, led the his  team with 95 defensive tackles. Jerrell Gavins, Ottawa’s strong-side  linebacker, won’t play after suffering a season-ending knee injury  during practice. Nick Taylor has filled in for Gavins. The Riders have  another edge here due to the performances of Muamba, Knox and Moncrief  down the stretch. 
Advantage: Saskatchewan.
DEFENSIVE BACKS
  The improved performance of the Riders’ defensive backfield is connected to Ed Gainey, who leads the CFL with 10 interceptions.
 Safety Antoine Pruneau leads the Redblacks with four  interceptions. He has been a steadying force because the Redblacks have  three rookies in the secondary — Corey Tindal, Winston Rose and Sherrod  Baltimore. Jonathan Rose’s only two interceptions of the season were  against Glenn. Still, Saskatchewan’s experience will be the difference. 
Advantage: Saskatchewan.
SPECIAL TEAMS
  Christion Jones was a spark for the Riders with two  punt-return touchdowns (including a game-changer in Ottawa) in just nine  games. Tyler Crapigna started slowly, with a crucial miss in each of  the Riders’ first two games, but recovered to finish the season with an  86-per -cent success rate on field goals. The Riders’ coverage teams are  led by Denzel Radford (24 special-teams tackles).
 Spencer is a dynamic returner and can also break open  a game. Ottawa’s coverage teams are solid and paced by Keelan Johnson,  who led the CFL with 29 special-teams tackles. Brett Maher had a success  rate of 82 per cent on field goals and led the CFL with a net punting  average of 36.2 yards. The Riders have a slight advantage due to  Crapigna’s success rate on field goals. 
Advantage: Saskatchewan.
INTANGIBLES
  No West Division team has crossed over to the East  Division for the playoffs and made the Grey Cup game since the format  was installed in 1996. That could change this season because the Riders  were 6-2-0 against East Division teams and swept a two-game road swing  by winning in Ottawa and Toronto.
 Home field hasn’t been a huge advantage for Ottawa,  which is 3-5-1 at TD Place Stadium. That shouldn’t matter as the crowd  will be behind the Redblacks and their quest to be the East’s  representative at home in the 2017 Grey Cup game. 
Advantage: Ottawa.

Keys to the game as I see them.  Establish running game early.  Keep constant pressure on Trevor Harris.  Have the hook ready if Glenn falters.  Take advantage of TOs.  With only one challenge, Jones needs to be cautious when deciding to throw the flag - he's not been very successful this year so making sure it is winnable and hopefully not early in the game will be very important.
As for the intangibles, Ed Gainey - our Ball Hawk and Christion Jones our punt-returner could be difference makers in the game.  May it be so.
