A healthy Keenan Robinson looks comfortable and capable of leading the defense as one of the starting inside linebackers. He's been able to absorb the scheme while being stuck on the sidelines, and thus far he has stayed off the training table.
Perry Riley, the fifth-year linebacker starting alongside of Robinson, looked inexperienced and lost at times against the Browns.
One three successive plays, Riley stood out in a bad way. First, on a play where he was covering the flat, he stepped up too far when Johnny Manziel looked to break the pocket. Then he bit on a pump fake, leaving his feet in the process.
On the next play, he locked his eyes on the backfield, flowed too far in the direction of the play action and then had to flip his hips and chase a play over his head.
On the following play, he incurred a facemask penalty, giving the Browns a fresh set of downs.
Luckily, Cleveland's offense was about as dysfunctional as one would expect, but to see Riley make those mistakes on successive plays is concerning. It is unlikely that he'll yield his starting spot because of it, but it may be interesting to watch the discrepancy between Riley and Robinson as the season progresses.
