Could work out, could not work out.
Cowboys need offensive line help terribly. What if there's a run on them? Threre are about 6 really top prospects there - Green, Johnson and Linderbaum at guard/center & Neal, Cross and Penning at tackle. Imo Dallas needs one of those. Sure, all 6 of those taken before #24 is somewhat unlikely. But there are so many teams with young qbs that need protection to be able to quickly blossom, not having to deal with getting sacked a lot is a great help.
Per one of the draft sites, I counted 9 teams that have OT or IOL as a need. That of course is 3 more than the available top talented OL players. Wouldn't take much for a run on those guys to wipe out all 6, now Dallas has to try and select the lesser-rated guys who have to "develop", and with players like T. Smith on their way out and players like Pollard nearing the end of their rookie contracts, I just don't feel Dallas has the luxury of time to develop players on the line. Continuity is big for the o-line, let's get a stud in there now...
