Mike Mayer's not easy to bring down. Even as a true freshman, he was pretty stout, and difficult to bring down when trying to execute a classic tackle to the waist.
He reminds me of Derek Brown, from the Holtz era, where many a defensive back was scared shitless when it came to trying to tackle him. He'd build up so much steam, in addition to having all of that raw strength, that just about every time, he'd run over defensive backs as if they were nothing more than a bunch of midgets.
I remember being at the 1991 Blue and Gold game, and seeing him catch a pass, and Jeff Burris trying to tackle him up high. After the collision, Brown got up quickly, and casually jogged back to the huddle, while Burris needed a few moments to steady himself.
