I may have a better answer for what the problem is with Alex Leatherwood. After the Raiders waived him, the Bears signed him. I read some analysis from a Bear's reporter that may explain things. He said that Leatherwood has all the physical qualities, is very intelligent, has a good attitude and work ethic, and no off the field issues. The problem is a profound lack of technique. He said most scouts thought he skated by on physical ability alone at Bama without developing his technique and skill set enough, and that got severely exposed when he got to the NFL. He said the Bears staff think they can teach him the technique and develop him into a very good lineman.
