This is a result of the "curse" of showing the yardage discrepancy earlier... when the Bills outgained the Fish 190-19 in yards... as soon as that happens the team with less yardage ALWAYS starts to gain yardage in bunches.
I know the D has been inconsistent, but the O has been brutal. If the O could produce some decent yds and points, all while killing some clock, the D would be much better.
That game was played not only right AFTER the holidays (Cristmas spending could've had an effect), but also it was only a week after the Bills got hammered by the same Houston team 27-3. The Bills were also without Jim Kelly (he got hurt the week before) and Cornelious Bennett, so I'm sure that played into it. It's not as cut and dry as you make it out to be.
The vid isn't a great representation of Evan's talent. Based on the original vid, I'd say he was a tall, but fairly mediocre WR. If you watch other vids it's obvious the kid has talent, but I'm not necessarily sold on him early in the first.
