You can get a solid OL in the second round. Or third. Or fourth, and so on. Keep in mind, Driver is pushing 40 now, and besides Jennings, there is great room for improvement.
Leonard Hankerson would have been a solid choice. Miami U standout. Listed at 6'3 209. One thing the Pack doesn't seem to want is a big, imposing receiver. He will most likely already be taken by round 2.
Derrell Johnson-Koulianos, Iowa standout, cleared of his legal trouble. has stated several times he would love to play for Aaron Rodgers, given the accuracy and consistent spiral. DJK broke every major receiving record at Iowa. Solid kick returner, great hands and a known big-play guy. Several scouting boards have said if it wasn't for his previous trouble, he had the potential to go late first/early second round.
Main problem, DJK has a lot of swagger and might be too flashy for the citizens of Green Bay, as he's known for his custom-fitted Dolce & Gabbana suits.
