Even though its a new position retaliative to the duties they do I think just have a separate SAM linebacker position. Your three nominees would be Ike Charlton Clint Kent and Moe Leggett
Yes this applies to older guys with more experience. There is a lot of U sport or lower level NCAA coaches making far less that kill for opportunities in a professional league.
I can see this cap being a positive. If you have to bring in some younger less experienced coaches you might get some real nice innovation. A young guy trying to make his name in the business will be more will to experiment and create something brand new as opposed to a older more established coach.
