If the Green Bay Packers could have any player they'd want at the end of the first round, then I'd want them to draft either a pass rushing outside linebacker to compliment LB Clay Matthews, or a pass rushing 3-4 defensive end who could replace DE Cullen Jenkins, who I expect the Packers to lose in free agency.
But based on the players who appear available, I'm still sticking with Mississippi State OT Derek Sherrod in the first round as a left tackle of the future. Here's what I wrote about him over at Mocking The Draft:
He has the size and athleticism to project as either a left or right tackle, and his excellent college career has shown that he's not a project. While his experience (50 games started in college) would indicate a smooth transition into the NFL, with the Packers, he'll have the luxury of spending at least one season on the sidelines behind veteran LT Chad Clifton and 2010 first-round selection RT Bryan Bulaga. Mike McCarthy has spoken very highly of Clifton in recent weeks, and the veteran had a solid 2010 season. But he sat out nearly every other practice as the years and multiple surgeries are wearing him down. He'll be entering year two of a three-year contract he signed in 2010, and I don't expect he'll continue playing after the 2012 season.
