Your team actually looks very good overall, but if I were you, I would be very wary of having Chisenhall as my only 3B option. He's definitely got potential, but he's a late-round flier, not a starter. You should probably target 3B-eligible guys for your last bench spots; I don't think the Indians will hesitate to make Aviles the 3B starter if Chisenhall struggles.
In a deep league like yours, I imagine Youkilis and Gyorko are gone, so you'll have to look at guys like Jeff Keppinger, Alberto Callaspo, or Luis Cruz. I like Keppinger this year as a Swiss Army knife bench guy (he's eligible at 1B, 2B, and 3B), you can plug him in wherever you need; he's finally got a guaranteed starting job and has been good for AVG over the past few years. Keppinger's also great against lefties, a skill Chisenhall noticeably lacks. Even if Chisenhall keeps his starting job, you may want to play Keppinger and sit Chisenhall when they face lefties.
If you could take a look at my team here
, I'd appreciate it. Thanks.
