While the Green Bay Packers needs at offensive tackle were lightened by the selection of RT Bryan Bulaga in 2010, it's still a position they could target with their first round pick. A couple months ago, it was clear there were a lot of offensive tackles with first round grades, but none of them stood out as the favorite. Right now, it looks like it should be USC's Tyron Smith.
Though he played right tackle in college, as Greg Gabriel points out, he's a former five star recruit who's coming out early, and he could become an NFL left tackle.
While pro days are designed to show off each player's best qualities, Smith's USC pro day may have cemented his spot as the top tackle because he weighed in at 310 lbs. He's had a problem getting over 285 while in college, but he's added weight while maintaining his athleticism.
He's not a candidate for the Packers since he should be taken early in the first round, but trading up is always possible. And it's very likely that GM Ted Thompson took a close look since he was in town making jokes at UCLA's pro day.
