I thought the outside runs were the bigger problem. Golston had a breakout season. Kneeland was drafted as a high end run defender with rush upside, Turner has the frame to be a good early down player, he is a bigger version of Kneeland. Think a rotation of those two will be fine at LE, my bigger worry is Parsons being disciplined enough not to sell out as a pass rusher. I think adding a bigger Mike LB in Murray should also help.
Would like to add veteran depth at both DT/DE to help the run defense.
