I think they can win anywhere between 91-95 games, pending on how the starting rotation holds up and stays healthy. Maybe they can add an additional starter w/ some extra cash like Ben Sheets of the Brewers. He'd look good as a third starter in T.O. The bullpen is another concern if they are to win over 80 games. Hopefully there aren't much blown saves this year.
As for the offence is concerned, they may not have powerhitter in the lineup, however it's more balanced (more clutch hitters) where they can all swing and chip away (National league style game). Another thing about the offence is that they have a righty-lefty-righty order (if Gibbons decides to put the order this way). This would give them advantage over other teams bullpens cuz they (opponents) wouldn't be able to have a lefty-lefty or a righty-righty matchup. But overall, I'm pretty optomistic about the jays fortune this year. They are probably a bat and another big starter from being a playoff contender, but should be fun to watch them this year.
