Kupp is the Rams 2nd best player and top 20 NFL player.
The Rams should have stayed game planning getting Kupp the ball and letting him make plays after the catch. Having big play makers is so Key to greatness of a team and with the decline of Gurley, Kupp is the straw that stirs the drink on offense just as Donald is that player on defense. You just can't find players like Kupp in a draft even with first round picks the odds are like 1 chance out of 5 that you can hit with a player that is so impactful. The entire defense has to game plan and take away Kupp which opens things up for everybody else if they take Kupp away.
On top of that, he has the "IT" factor. A guy that just has it all. Two steps of everybody on game day, instinctive, prepared, student of the game, and so productive at key times in the game, making key first downs and the big game changing plays. He is like the ultimate decision maker and can improvise and read the play and make the right decision every time where it is an adjustment to a defensive presnap, a key block, a route adjustment, any decision to be made and he is more often going to be in the right. Throw out all the good stats and you still have a "winner".
His value skyrockets, because on top of the obvious, he has all the intangibles!
When Peyton Manning says, he would want Kupp over any other WR, that is like the master of football putting the exclamation point on Kupp's value! He is the truly, the chosen one!
