I'd say he had about 5 extremely good seasons for the Bills and that was when the Bills were in their prime going to Super Bowls every year. It might be a different story had the Bills won a couple of those Super Bowls but he didn't stay on to have the longevity Bruce, Thurman, and Andre had. Biscuit was a huge component to the Bills success though, so many people forget about the season he had in 1991 when Bruce was injured most of that season and Bennett just wrecked havoc(he won AFC Defensive player of the year that season)
