Saying the Bills coaches improved Henderson's play is like buying a Ferrari, placing new tires on it, and saying "look, I made a racing car".
Henderson was one of our best o-linemen in preseason, enough to earn him the RT starting job. That's a testament to the young man's effort and talent, not coaching. And if he improved during the year, he did so in spite of the current offensive coaches.
Sammy, the best WR in college last year. The cream was going to rise to the top no matter who was throwing him the ball.
