Spiller has had normal ups and downs as a rookie runner--- the more repetitions he gets with the ball the more he'll learn to trust his instincts. If he were given 20 carries per game or so he'd probably be accruing statistics at an acceptable rate, for fans. But he was brutal at picking up the blitz early on and in that regard he has improved steadily. Yesterday was a perfect example of what Gailey is doing in developing Spiller--- he's kept in the backfield on passing downs and allowed to learn through repetitions how to read blitzing 'backers and DBs, and stunting D-Linemen. Why burn him out with a winless team when Fred Jackson is averaging 4.5 yds/att? If they needed him to be the guy, he could be the guy. But there's no reason to burn him out.
Jahvid has had one terrific game, but he's basically just getting more overall touches at this point, not to mention he's only averaging 3.2 yds/att. Should Detroit fans call him Jahvid Bust?
