You gotta give him another game or two before making any judgments, good or bad. You can't overlook the fact that he came in fresh against a defense that had been out there all game, and his big TD run came after the result of the game had essentially been decided. At the same time, it was his first live action in years, and he looked good for a guy getting his first D-I carries.
Our problem at HB is we have a room full of guys who all have a strength and a weakness, but nobody who is the all-around answer. Keion Davis is an incredibly fast straight-line runner, who can rip off big gains so long as the hole is big enough, but if someone is waiting on the second level, it stops his momentum and he struggles to evade/adjust. Anthony Anderson is a big back, a wrecking ball you throw right at the d-line, but is never going to outrun anybody. Trey Rodriguez is shifty, but he's either too much in his own head or has really poor field vision, because he can't seem to find a line.
Hopefully King can emerge and stay healthy and be that all-around back. I am usually one to say its presumptuous to imply we know something as fans that Bill Legg doesn't know as a coach, but one thing he does that baffles me is the seemingly random way in which the backs are used. Every once in a while, you'll see Anderson in a short yardage situation, but sometimes it feels like they just have bingo balls churning next to the Gatorade cooler, and whoever Doris pulls out of the trap is who goes into the game.
