Remember that Chacin shut down the Yankees in NY in his ML debut last year? That being said he could also crash and burn on any day. He could be great or terrible, he's a little flakey at this point in his career.
Stay away from Towers. The man you should be targetting in Bush. Very solid youngster who may not get a lot of wins but will put up decent ratios to help you in a deep or AL-only league.
I'm going to the Game on Sunday so I will get to see Chacin first hand and see what he is all about. I also get to see Matt Clement and sit and wonder if he would have got the win in the cubs second game against Arizona.
Chacin is so aweful that he was 19-2 last year with a 2.80 ERA and 1.15 WHIP between the minors and majors. I know he's not great but you have to give him some credit. Seeing him pitch once and not liking it doesn't mean much unless you're a scout which I really doubt you are.
"Jack, will you call me, if you're able?"
"I've got your phone number written, in the back of my Bible."
Chacin is interesting. A prospect five years ago, but never got any better. He learned to throw a cutter last year, and has been very effective ever since. I'm still real leery, but you can't argue results. Might be worth rostering deep leagues until he crashes and burns. And who knows, maybe he won't.
Bush is the most reliable of this trio. He'll likely never be more than a middle of the rotation type, but he's got a sound arm and decent command. No reason he can't win a dozen with a low 4 ERA.
Towers has less than average big league stuff and can only survive with pinpoint control. I would urge staying away.
