Offensively, the Jays were amazing in 2006. Reed Johnson, Frank Catalanatto, Vernon Wells, Troy Glaus, Lyle Overbay, Alex Rios, Eric Hinske, Shea Hillenbrand, Bengie Molina, and Gregg Zaun. Pitching wise, Burnett missed a good chunk though, and like you said Towers and Chacin came nowhere close to their 2005 seasons and s*** the bed. They only had Doc and Lilly in the rotation until they got Burnett in June. Outside of those guys, they had no other viable SP options. Janssen as a starter looked alright in his first couple of starts, though he wasn't reliable. BJ Ryan was lights out as a closer. Also, defensively, the Jays were a bit sloppy. Russ Adams was awful.
Boston and the Yankees were still power houses which made it tough for the Jays to break through.
