I just watch a lot of college ball every year and by the time I do that and see a lot of sportscenter in February through April, I feel like I have at least a grasp on most players drafted in the first few rounds, and some name players who go later. It is too late for that for you though.
Bowl season is a great thing for viewers. You can get a glimpse at a lot of these guys. And I mean all bowls, not just the big BCS ones, although those are great too.
This weekend there aren't as many games as a normal Saturday, but you will see plenty of future NFLers in LSU/Georgia, Michigan St/Wisconsin, Virginia Tech/Clemson and Oklahoma/Oklahoma St.
