Jumping in on this topic for a second, regarding the value of the 12th pick for miami....its to me a tough pick.
I feel the player at 12 wont be perfect,who ever he is will come with some reservations(incuding mcclain IMO) as for the debate over Odrick or a DE later in the draft, on the surface the strenght of the defense seemed to be the DL a closer looked reveals the rush D suffered from '08 to '09, also the progress of the younger DLmen I feel didnt occur, Merling seemed to regress Langford was quite and Dotson again made very little contrabution.
So I see the reasoning for possibly drafting a DLmen at 12, however there are other areas on the defense that are more pressing.
ILB is a must this area has to be upgraded or there will continue to be poorus defense played, now the tough part, IMO you should ask if player X lets say McClain fits a need & player Y lets say Odrick fits more as an upgrade, two questions need to be asked then answered before challenging the pick as good or bad.
1-how much difference between X & Y in terms of ability and contrabution to your team?
2-what other players can you get to a-fix a need & b-ugrade a position?
To me upgrade vs fix are two different matters, as mentioned Langford,McDaniel,Merling to this point are servicable can you win with them yes, however the "need" at ILB and lesser extent OLB is to me a "fix" those positions are broken.
Thus the value must be whats the difference between getting a need(fix) or an upgrade, Im not sure at this stage miami can afford with the 12th pick to upgrade, just my point of view this should be a fix player and there are enough positions that need fixed that they can find a good/great player at that position, unless a player is a "great" cant miss prospect then drafting to upgrade is a mistake.
