yeah you definitely can't drop him. but honestly, i think he was being liked too much by some people in drafts. how is he different from kerry wood now for fantasy purposes this year?
say what you will about kerry wood, but he does give you 100+ innings per season, and except for his worst season always gives you sub 4 ERA and bunch of Ks. even in his worst season, he still K-ed a ton and had like 1.10 whip or something. what will AJ Burnett do this year? coming back to the AL East, i doubt he finishes below 4 ERA and Ks at a rate of 1 K / 1 IP. and this guy was drafted in like every single league, while kerry wood was often times a FA pick up.
i'm not saying i knew AJ would be as worthless/valuable as wood this year, but i did know he was the kind of guy you let someone else take a risk on because their values on inflated and aren't worth where you'd have to draft them to get them (ala bonds, prior, dontrelle, etc. admittedly, i also had carpenter on this list as well, but 3 out of 4 isn't bad).
i predict that when AJ returns, he'll give you around 4.10 ERA, 1.20+ whip, at best 7K/9IP, and some Ws. this is if he doesn't go back on DL. wood will give you 3.50+ ERA, 1.10-1.25 WHIP, 9K/9IP, and less Ws than burnett. all in all, i wouldn't care who i had, except for the fact that if i had wood it'd probably be for free. (hmm there's a joke in there somewhere ....)
