I would have drafted either Barwin or Sintim instead of Brace for 2 reasons:
At the time of the draft, there was no talk here about playing a base 4-3. Therefore, I didn't see the need to use the #40 overall pick on a perceived backup NT. Not that Brace was over-drafted; he was a consensus mid 2nd-rounder. And we def. needed a quality backup, because Mike Wright should be nobody's idea of a NT. But at #40 overall? I might've used #94 last year on Red Bryant instead.
The other reason is that at the time, we needed - and IMHO, still do - young talent at OLB, esp. at 3-4 OLB. Nothing that has happened this pre-season - incl. the panic trade for a poss. washed-up Derrick Burgess - has caused me to change that opinion. Woods & Crable inspire Zero confidence, and TBC & Ninkovich are merely stop-gap 3rd-stringers.
As for SeaBass: if there had been a poll, taken the day before the draft, which asked those of us in the Draft Forum whom would they choose btwn. Beatty & Vollmer, I wouldn't have been surprised if the choice of Beatty had been near-unanimous.
Naturally, I hope that Bill's right & I'm wrong; but as you said, it will be interesting indeed to see how things turn out.
