Despite his smallish stature, Brian Westbrook was a very strong and physical back. Not only was he arguably the best best pass blocking back in the league, but he was known to deliver some nasty stiff arms and big shots to would be tacklers...
This is not a highlight 49ers safety Mike Adams is ever going to want to see again...
Then of course, there was that time he just ran over Jonathan Vilma, who has 30 pounds on BWest.
