In 1997 and 1998 Glenn was widely considered a shut down corner and teams RARELY threw to his side. At that point, he was a top 3 corner league- wide, and if not for the scheme change, the jets impending salary cap doom, and a few hampering injuries...he may have ended up being a borderline hall of famer. Unfortunately he faded away from 2000 on.
No way, he played some of his best football for the Texans between 02-04. Was used a bit differently with the Cowboys but still played well the last couple of years. AG was one of the best CBs the Jets ever had....
