I agree with NewEra. There is no switch. While a ton of hard work may yield the same results, there is no magic switch where the offense just starts lighting it up again. It's just hard work and getting better execution from hard work. Less mistakes because better decisions are made from that hard work because maybe they understand better what they are supposed to do. Or Dorsey just runs a better offense that these guys are better suited for. But there is no magic switch.
When other teams "get hot at just the right time," that wasn't a magic switch either. It's just the guys executing better what they practiced all year or maybe even a change of philosophy to suit what they did well for most of that year... or both.
That isn't the first player that has said its the most complicated offense he has ever seen. Maybe thats part of the problem with this offense. I have heard that comment at least twice before.
Hines played on ST returns. That is why he started right away. Having one play for him isn't anything ground breaking. I do think it takes the Bills time to get players involved. It doesn't take much to have a package of plays designed for a new guy. To me it seems the ones that start right away are out of necessity for the position. Returner was a necessity at the time. The other choice was Hyde just to fair catch, or McK where ya might cringe every play looking for a muffed catch.
