According to a story by Chris Hummer for 247sports, the NCAA Division 1 Council will hear a proposal for rule changes in Indianapolis on Thursday and Friday.
Among the proposed NCAA rule changes are adding a 10th full-time assistant coach to football coaching staffs and a second national signing day.
10th Full-Time Assistant Coach
I see no problem in adding another assistant coach. Like Hummer says in his story, pretty much every team in the country has a QB, RB, WR, TE, OL, DL, LB, DB, Special Teams coach, as well as the head coach coaching one of those positions.
