Partially disagree with you.
I agree that we need to keep Hunter healthy, but running 5 or 6 different players in a game can be hard on the o-line. Each player runs with a different style, awareness, speed, and other tendencies. Now that we have played 4 games, I would personally like to see 3 RB's used until the very end of a game (when the game is already settled).
In my opinion, Hunter should be getting 12-16 carries, with Tamerik Williams getting 8-10 carries, and Kobe Johnson getting 4-8 carries. This doesn't mean that we don't use Dom Gonnella, Jalen Bussey, or TK Marshall at all, but I would prefer for the o-line to have a better opportunity to "gel with the runners" during the game throughout drives instead of rotating RB's every 2 plays.
(I look back the Lance Dunn/Bruce Anderson/Chase Morlock years - it was 3 main guys, with some King Fraiser mixed in until injuries took over, but during the playoffs the o-line was humming because they knew ow each man ran and it really showed)
Having said this, I will say the current rushing game is working well, so we don't need to fix something that isn't broke, but it is just my 2 cents.
