Sean Taylor is the first name that came to mind. ST wasn't just a heavy hitter; he was simply a explosive player. To the point anytime he got near the ball you expected something special to happen.
Second name was Jonathan Vilma. Reminded me of legendary safety Jack Tatum in the way he could run through guys.
Speaking of safeties, when Ed Reed wasn't getting picks, he could lay the wood.
Ray Lewis was sort of a Butkis-type hitter. In the NFL he became known for crippling guys, but when he was here, I thought of him more as a Dan Morgan - a physical, athletic, sure tackler.
Incidentally, Ted Hendricks could hit hard, but the Stork was more of a sure tackler than a power hitter. Once that 6'7 Mad Stork got his hands on the ball carrier; it was over.
Micheal Barrow was a power hitter, and the Vanover hit will live in Canes history forever.
Hard to choose just one, ya know? xD
