For me, longevity plays a role. Terrell Davis was the best in the league for a few years, but then he got hurt a bunch. It's a shame, sure, but I wouldn't put him in the Hall even though he had a few years that showed he was probably heading there if he stayed healthy.One in 16 seasons, the other in 7.
It's not his fault that he had a career ending injury. When he was active, he was arguably the #1 or #2 receiver, for his whole career. The same can't be said, IMHO about Carter...
