IMO, P1's 2nd pitch is a fatal flaw.
P2's durability & makeup are fatal flaws.
P3's vR is a fatal flaw.
2B1's vR isn't horrible, but I'd want better in such a key rating at 1st round, 1st pick.
2B2's vR is a fatal flaw.
2B3's durability is a killer (~400 AB's a year?), and won't hit for much power.
P4 is the "last man standing," in my opinion - and looks like he'd be a stud SP.
