Far more, in fact, than a good 40 time. I'm not particularly interested at how fast someone can run 40 yards in a straight line. Has nothing to do with football ability or football athleticism. The shuttles and other positional drills actually give a (slightly) truer reflection of footballing athleticism in my opinion.
