offensively, crede has a ways to go before he's considered as a solid cornerstone (literally) of a fantasy team.
last year he was... i wanna say .260/18/75? i remember he started off piss poor then by the 2nd half was good enough to get to where he was.
his defensive prowess is going to keep him in the lineup as an everyday 3B. the sox radio guys think he'll steal a gold glove or two from chavez before its all said and done... that said, his 2002 #s got everyone excited.. .281/12/35 in like 53 games.
he CAN hit 30/100 but its going to take him awhile. not right now, as he's like.... low .200s/3/10 or something.
best bet is like .255/20/75 this year.. at some point i think he'll be a 25/100 type guy, but not for the foreseeable future. so i'd keep an eye on him and if he gets red hot he'll have plenty of rbiops with that lineup, but for right now you'd be better suited with a more established 3B type guy. if you're using joe crede as a starting fantasy 3B, odds are that you can roto him and others and try to get a conglomerate of 3Bmen who will get you .275/25/80 until he Himself can do it on his own.
