Browner was a defensive end who could manhandle offensive tackles and guards with sheer power, out-leverage them, or finesse his way around them. Even when he got double teamed, he could still beat his blockers.
He could also beat most linebackers in a foot race.
He was a one man wrecking machine who you'd have to assign three blockers to take out of the play, and if you did that, then someone else was going to get through pretty quickly.
A 100% healthy Stephon Tuitt with better footspeed who would have stayed for his senior year (none of which happened) might have been the closest thing we could have had in comparison, and even then, Browner would have been a couple notches ahead of him. .
