Unless he works out with Hardy during the off-season and "puts on" 20 pounds of lean muscle, Norman is no Safety.
TD could transition back to Safety before Norman could.
Davis as a Safety...................hmmmmmmmmmmmmmm.
I have thought of Davis back to safety too, but He probably does not want to drop the 30 lbs-. Norman would need to add some weight, but there are smallish safeties. Mike Minter was 5'10" 195. Not saying Norman is Mike Minter,
There are many Cbs who make the switch. I am basing the statement on 3 factors--
1. He seems to tackle well
2. He is best when facing the LOS
3. He is a ball hawk
4 (bonus) he runs about a 4.6 (supposedly) which means to me that he has adapted by reading and anticipating quickly. Slow for a CB, but for a S, he would not be. Not perfect and I do not see his frame holing up at S, but if he busts at CB, why not take a look?
