The Heisman race is almost settled, but the debate about how the five finalists translate to the NFL is just beginning. Our NFL draft insiders, Mel Kiper and Todd McShay, go back and forth on each player -- what they do well, where they can improve and where they could be drafted. Lets dig in.Lamar Jackson, QB, LouisvilleKiper: Lets get this out of the way: I dont view Jackson as an NFL quarterback prospect?at this point. Hes an athlete -- a phenomenal one at that -- playing quarterback, but I havent seen consistent NFL-level passing skills. Jackson has completed only 57.6 percent of his passes this season (54.7 in 2015), and thats a huge red flag for NFL teams. If he cant complete 65 percent of his passes in the ACC, what optimism is there for completing 65 percent of his passes in the NFL?McShay:?I think he has some Michael Vick-type qualities. Jacksons rushing ability is obvious (1,538 yards and 21 TDs on the ground) and he has really good arm strength. He can make any throw you want from a velocity standpoint, but youre right, Mel: Jackson leaves way too many throws on the field right now. (Vick did too, finishing his college career with a 56.0 completion percentage.) Beyond the accuracy issues, the biggest area Jackson needs to improve is in his footwork. Nike React Cheap Online .
