The thing you should do is take the performance of a player you like in one game and use it as an argument for him being better than that other player you don't like so much.
Joseph Yearby 156 carries, 797yds, 5.1yds/carry, 5td
Mark Walton 97 carries, 383yds, 3.9yds/carry, 6td
Not to say that Yearby is better, but cut the crap. Both have performed well, and neither has done enough to be clearly better than the other.
As for Kayaa...
184 comp, 298 att, 2458 yds, 61.7% comp, 13 td, 4 int
Quit blaming the best players on the team for not being quite magical enough to win every game. This is a guy with a bad OL and a truly terrible defense, so hows about you lay off? Everybody gets a shot, and if JA or one of the guys already here look amazing maybe one of them can have the job, but until then it's Kayaa's job and you're a fool if you think it shouldn't be.
