I sadly agree with you KW13. Your point is not insignificant. And this is the way Snead will see it.
Kupp can still play and even start if need be, but time/injuries etc invariably have taken their toll on Kupp, who is at about 90% "vintage Kupp" and that percentage will drop further next year. What an amazing player he has been! But...time moves on....
This leads me to my next point; the Rams will take a what they believe to be future elite WR in round 1 or round 2 of this year's NFL draft. It's absolutely imperative that THE core strength for the Rams -- their passing game -- remain elite. This draft is loaded at WR. In addition to a very early round WR, the Rams will draft DB's (corners and safeties: at least 3 or 4) early and often, and add a tackle somewhere, and then best player available.
