AJ Jefferson is a solid CB, this is a good move by Minnesota and not a good one for Cardinals. He was mirroring WRs better than any other CB on our roster. If he had ball tracking abilities he could become a top CB. However thats the problematic part of the position, the hardest in NFL. Not only you have to blanket but also be able to find the football. PP has the reverse problem at times.
In many regards he reminds me of a more athletic Rod Hood. He will never be a great starting CB because he cant locate the football. But his ability to mirror the WRs is a very good ability that many dont posess. Also he is young and with experience he can learn more on how to play the pass better, find that football. Its a shame to give up a solid servicable cb with an upside for what probably will be just a minor change in pick position. Minnesota is terrible at the position, they upgraded the unit with this move.
