He uses whatever scheme he thinks is going to work at the time. And not just from game to game, he changes from play to play. Some of things he runs:
Single high safety or Split safeties
3 down DL or 4 down DL (1 being a 34 edge rusher with his hand in the dirt ala Fowler)
man coverage and zone coverage
I wouldn't worry about him being a fit. he'll fit, the thing I worry about is how long would the Rams be able to keep him when he succeeds.
