While the NFL Combine is going on now, the NFL draft is still two months away. The Green Bay Packers have an excellent college scouting department, and their schedule isn't impacted by a Super Bowl run. But the coaches are involved in the evaluation process too, and they're at least a month behind their colleagues that did not make the playoffs. From Jason Wilde at Channel 3000:
"I’m going to have to apologize, because I’m very behind in the draft as far as looking at college players," McCarthy said. "But I’m looking forward to breaking those guys down. We’ve always taken a close look at all the quarterbacks, you can never have enough quarterbacks, I don’t think we’ll be picking one in the first round this year but we’ll definitely take a close look at those guys."
Maybe this will prevent him from taking a close look at every available player, or maybe it's a benefit that he doesn't have time to overanalyze each one.
