I think it is a league wide problem. Cost is probably the leading reason, followed by all of the rule changes. I am all for making the game safer, I cringe when I see a player go down and not move, but let's be honest, it's a dangerous sport, but some of the rule changes although they were made in an attempt to make the game safer, have made it less exciting as well.
Any WR drafted has to develop in the NFL.
Just the talent level of defensive players in the NFL makes it very hard for a rookie WR to come in and make much of an impact.
There are not many WRs who come into the NFL and make a lot of noise consistently.
I’m telling on myself, but I remember Memorial Stadium in Baltimore.
The C-O-L-T-S chant was so loud, each letter echoed over the next. I thought they tried it in Indy years ago (they added Colts! Colts! Colts! at the end), but it faded out.
