I understand what you're saying but don't agree. For this RB, I had to ask for more playing time on the front end of this season. Here's an example.
http://goallineblitz.com/game/game.pl?game_id=50213915 plays. Even with that short total he ended up with 400 total yards 8 TD's against the 4th place seed in that conference.
Also, the power back/ second string guy on our team received 277 touches this season. it's not all backside, all the time. He carried a huge load and played a role in our success.
I'm not a fan of all speed is what I'm saying. the case I was trying to make is 99 speed and nothing else will not make you a star. I know I'm playing against LB's that have 90-95 speed but I promise you this.... None of them have as many points as I have in quick cut and first step. Straight line speed is one thing, turn around and catch the RB speed is another.
