Huff is definitely one to avoid drafting, no matter where you might have him projected... whether that's because he's a second half player (which I still believe - I'll definitely be watching him around the ASB to see if he might be worth a pickup) or because he just sucks.
Eli Marerro has been a 1st half (actually, 1st month is more like it) player most of his career. Most people, I think, consider him undraftable at this point, but if I had an open roster spot and no clear needs, I might take a last-round flyer just to see if he comes out of the gate strong. He wasn't horrible even last season, at the beginning. He hit .303 in April, with 4 HR, 9 RBI, 7 R, and 3 SB. And then at the beginning of May, like a faucet, he shut off. If he's got a roster spot to start this season, it could happen again. Probably as much chance as Erubiel Durazo has of tearing it up this year, maybe more.
Shelton was a first half guy last year... again, it might happen again. Who knows?
Seems like most of the guys that you could have definitely considered one-half players are closer to "completely undraftable" this year. Shawn Green is another that comes to mind. ARam is one that's still up there, but let's face it... if he's available around the time of the draft that you've got him ranked at, you're probably just going to take him, and you're not likely to get rid of him even if he starts slow (no point in trading a guy when his value's at a low).
(taps little picture of a microphone)... is this thing on?
