actually, the NFL is a much different place than it was when Rice was piling up his statistics. The rules have changed to benefit the offense....especially when dealing with contact.
So....Colston (and many other players) will probably get stats that may be a bit blown up as a result. I realize that this actually makes what Rice did even more special......but since you want to base it on stats.......that's all I have to offer. Rice also played with some pretty good wideouts in his time with the niners.....and also played in a true west coast offense (like Colston)
Thier careers may be very similar......hopefully for us.....because that might mean some Superbowls.....(hey, a guy can dream...no?)
