re: Do you think TM at safety puts him in a better postion

Depends on the scenario.

I'd say a Tyrann back at Safety against a Alabama wouldn't be as effective as him up at the nickel. Really in the Bama game I think the players of the game should have been Eric Reid and Brandon Taylor. Both the safeties played downhill and made game changing tackles on Richardson.

Against Arkansas which likes to run 3+ WR sets. A play maker back at safety like Tyrann could be beneficial. Especially with Ron Brooks being pretty impressive as that rover nickel.

Think of this 3rd and long package:

DE- Sam Montgomery
DT- Michael Brockers
DT- Bennie Logan
DE- Barkevious Mingo
LB- Ryan Baker
LN-Tyrann Mathieu
RN- Ron Brooks
LC- Tharold Simon
RC- Morris Claiborne
S- Eric Reid
S- Brandon Taylor
