I am wondering if Bama and some of the others have been using these extra positions for quite awhile. Bringing Coach Riley does give us the benefit of all his past coaching knowledge. I am all for taking advantage of every rule, not breaking them. I think the SEC has been doing this stuff for a long time. Not a slap at the past staff, just too much to learn, and too many loop holes in the NCAA.
I would say this type of number addition has been going on since the middle of Frank's time here. I am sure Urban takes advantage of every rule there is. That is good , and I think we are seeing what experience brings to the table so far.
