I think it’s more a lack of playing time/experience in camp vs. a lack of ability to ever play the position on those downs. He’s got the motor, range and decent instincts. He just hasn’t had the reps against various coverages in live action to make the coaches comfortable enough with him just yet. If the unthinkable were to happen to put Brooking on the bench, I bet you’d see Lee get the snaps to learn on the fly…especially if Williams & Williams continue to struggle.
