When Mayock talks about quicker than fast, Riddick is that too a T.

Quicker than fast usually means this guy has a big discrepancy between their initial burst or in and out agility versus their straight-line speed. You see a guy like Tavon Austin whose agility is incredible you hope it translate to straight-line speed, and in fact it does. Riddick makes some of the most explosive moves in space but once he gets out, there isn't more giddy-up. Which isn't horrible because many NFL RBs are like that.

coming out of Florida. But he could burst into and out of the hole very quickly

Surprised that someone could break rushing records at ND and not really be wanted in the NFL.

Riddick has great change of direction but his top end speed is average - didn't he break a run against BYU only to be chased down from behind?

Atkinson is very fast, but he does not change direction well. I think this is why Atkinson's runs are generally sweeps or draws, because if he ever gets behind a defense no one will catch him.

In terms of agility, Wood was more balanced.

I suspect if he's healthy he'll run a little faster at the pro day. Riddick is quicker than he is fast. I always thought Wood was faster and Atkinson clearly is faster.

(with apologies to Lou Holtz)

ND running backs of all time. He showed FSU that beating him in a footrace and tackling him were two entirely different propositions.

when asked why he was so durable he replied "Well, you can't pull fat."

and he has to grow into the position to ever be as good as Riddick was.

I learned what a clutch player Riddick is this past season. That is something to value in an athlete. ND would not have gone undefeated if Riddick hadn't squiremed and stretched with all his might on some very important plays.

Woods was faster too but you sometimes wondered if he used all his talent; something you never wondered about Riddick. I'm not saying Woods didn't try, just that Riddick seemed to go the extra mile.
