Great teams, like the Blue Jays of the late 80s and early 90s.. the SF Giants of the last few years... or the Kansas City Royals now aren't one shot wonders. They work their way up, and comeback time and again until they take the championship.
If Toronto manages to keep the core of its team together.. and improve what it needs to (notably the bull pen).. it'll be back. It's still imho one of the top 3 teams in baseball (along with the Royals and the Cardinals). See you next year.
Congrats to the Jays on a great season... totally engrossing entertainment in the last half and playoffs.
