Yes, thise are some good WRs who are less than 6'. Note, only one of these players (mason) is in the top 20 in recieving yards. Also note, these players are on teams with a combined record of 20-40.
However, these recievers are the calibur I expect Lee to develop into...The solid role player, who helps a team alot, but is not a household name and will not draw signigant attention on the field. I just dont see him being able to be a #1. For that role you need a big physical WR such as TO, Moss, Walker, Moulds etc.
Now enough about Lee. The kid had his best game ever today, and I hope he proves me wrong...Congrats to him. GO BILLS!
