i hadn't heard about vladdy's elbow... that kind of worries me if it is indeed true.
typically, vlad is a mid-late season player. he'll put up solid #s early on and get stronger and stronger down the stretch. he was hitting .350+ over the last month or two, which propelled him past soriano as the #1 overall player in fantasy baseball.
i hope he doesn't have a lingering elbow problem, although that would explain much. he hasn't had to run that much this season (6 or 7 SB attempts?) but his average is way low, and his HR/RBI #s are somewhat below what they should be (6/23 whereas i think normally he'd be like 8-10/30-35). so i wouldn't call him a bust just yet... but if he's hitting .270 when june rolls around, then you might have reason to be concerned. it could be 2001 all over again, which was, save steals, his worst season since starting to play full-time.
