I thin everyone is getting carried away. Spiller is very good but he still has some limitations. He won't finish his runs strong, he has lots of negative yardage plays, he still hasn't shown that he can handle 25+ touches or more on a consistent basis and he has shown a tendency to fumble. Spiller may solve some or maybe even all of these problems and really become like Barry Sanders but he isn't there yet.
I think the team clearly missed Jackson vs Miami and the combination of Jackson and Spiller is still far more effective than Spiller alone.
