the first thing i see is that your going to need someone to cover ARod while he is on the DL. Teahen could be ok there but is he certain to get regular playing time with KC? i know they are interested in him playing 2B, but his playing time could depend on how he adjusts defensively to a new position.
Bourn is interesting. he should be better than he was last season. his career minor league AVG is .285 and he did have one season where he hit .317 in 2004. im thinking he should be able to get the AVG up to the .270 range.
i like the starting pitching. i think Harang should bounce back to his regular type numbers in 2009.
i think maybe you could use a more reliable closer. i dont trust Bell. his home numbers- 2.33 ERA, 0.93 WHIP. his road numbers- 4.81 ERA, 1.47 WHIP. it was 2006/2005 when he was with the Mets that he had back to back seasons with an ERA in the 5's. he could get a good number of saves, but i dont think his ERA/WHIP are going to be pretty.
