As in, smart, heady, always ready, knows where the play is going, fills the right hole . . . but, far more likely to get TO the ball carrier before the ball carrier gets to him.
Both guys, one could say, aren't "elite" athletes. Solid. At least average. Not "elite." But they make this work on Saturdays/Sundays. They overcome their athletic limitations with smart play and awareness . . . and "want to."
Anyway . . . this is all too soon to say or predict, of course. Kiser hasn't played a down of NFL football. But I'm gonna go there anyway. He's going to be JL, but better. He's going to look to penetrate the offense, find the ball, and make a play. JL made tons and tons of plays . . . but he wasn't really the heat seeking missile type.
For next time: OO as Wilbur Marshall.
