Here is my take. He definitely has the physical tools. I feel it is the mental approach that he is lacking. Mind you i didnt say intellectual approach. Its about a mentality. Ive watched him react on the sideline. Ive watched him react after a bad play. Ive watched him plenty to see that he doesnt have the machine/robot/ultra-intense thing that the best middle linebackers in the game have. Lets just talk Iowa. Station, Angerer, Jewell, Morris, Hodge, Hitchens, Kirksey. Lets talk all-time. Butkus, Singletary, Seau, Nitschke, Lewis, Lambert, Ham, LT. With the "possible" exception of Lewis, who was as unique as you get and literally a stone cold killer on and off the field, and LT who had a little fun but was more focused on building rage for the opponent as the Giants offense was on the field, all of these guys are intense, focused and oblivious to celebrating and smiling during the game.
I just think his mentality is more of a defensive back or wr, people who talk and showboat. Im not saying that cant be part of his game, but a lot of programs need that guy to be the one that the rest of the team says, im glad he's on my side. The fear that he's putting his life on the line every play and i dont want disappoint him. I think its apparant that the coaches have noticed something similar. The UNI or ISU game he about had to get checked into a straitjacket he was so lost. BF had to calm him down during a timeout. He doesnt have IT.
I hope that he's wildly successful even still. As a former coach, im looking for the Hockaday or Ben Niemann or obviously anyone on the list above. No energy for anything but putting your body on the line every play.
