Eh, if the value isn't there, sure. Part of my logic is that there's going to be a first-round run on two or three positions -- offensive tackle, and either defensive end or wide receiver. Maybe both. But that's going to push down some good value at guard, defensive back, and linebacker. On that note, Gilbert might not even be there at 51 (the draft's still a month away... this stuff is way too early to even talk about credibly), but let's go ahead and assume he is.
I think it's highly likely that Levitre, Robinson, or Urbik is on the board at 51. I personally think that tackle is a bigger priority for the Boys (Flozell is one of the oldest starting tackles in the league... it's time for a contingency plan), but the value probably won't be there. At least seven OTs will have gone off the board by then, if not more. There may be pretty good value at center, too, but I don't want to start that discussion. It'll get ugly quick.
As far as inside linebacker, Maualuga goes in the first round and so does Laurinaitis, in all likelihood. But I'm not sure that many teams are going to be looking ILB in the first half of the second. If that's the case, there should be some decent guys on the board, but you'll probably get better value in round three. Everybody knows the hot names here, so let's move on...
At DB... Delmas is gone by now. Period. So are the top five corner prospects. But there are some pretty interesting names that should be left, and we're borderline dangerously thin in the secondary. Just admit it. If Newman goes down again, we're one injury away from a nickel package crisis. You can't go 16 games or more praying that two people don't get banged up in the secondary. Odds are it's pretty much going to happen. That said, the argument here is whether or not the true value lies in the second or third round.
I think we seriously consider drafting another receiver also. Jerry wanted one in the second last year. Miles Austin hasn't changed anything since then. People were quietly saying the same things about him back then, and now we're minus TO. Yeah, yeah, Roy Williams, I know. Whatever. Like I said, if Brian Robiskie's still on the board at 51, I think he represents a better value and has the chance to make a bigger impact on the team than a backup DE. Although, I'll admit, I think he probably goes early second, along with Kenny Britt and Heyward-Bey (Not a first rounder, despite what ESPN says. And if someone does take him that high, it's a reach.). Of course, Jarron Gilbert might be just as likely to be gone by then too, so... it's all "what ifs" at this point.
