If you want the Rams to draft a guy like Kupp, who enters the NFL knowing how to run routes and the small details of playing the position, root for the Rams to draft Van Jefferson out of Florida. He'll be 24 when the season starts, but needs almost no development.
I think Tyler Johnson is a better version of that. Van might be slightly more athletic, but Johnson is more physical and stronger. I see Van as like Brian Hartline. Great route runner with good quickness, but he lacks physicality and is too easily disrupted by physical CBs who can hang with him. I say that as a Gator fan.
I would compare Tyler Johnson to T.J. Houshmandzadeh. He's not going to burn you deep, but he'll be a headache in the short-to-intermediate ranges. He's 6'1" 205 with a bully mentality, can win contested catches, blocks well, and is a really phenomenal route runner. But what I love about Tyler Johnson, and it's the same thing I loved about Cooper Kupp, is his football IQ. He sees the field like a QB. He understands the big picture of what the offense is trying to do, can read the defense pre-snap and recognize what it's trying to do, and then will alter how he runs his route to help his QB out.
Kupp is an outstanding slot WR.
But, while I'm sure I'm in the minority here, until I see him play outside and beat #1 & #2 CB consistently, I'd say he got drafted right about where he should have been drafted. The top of the 3rd round wasn't a bad spot for such a selection. That is, unless there were teams desperate for a slot WR who passed on him for other slot WRs earlier.
Or course, I wouldn't spend a first or second round selection on the greatest slot WR.
That's a little shocking, Memphis. If a guy can give you 100 catches, 1400 yards, and 10 TDs per year, do you really care if he's doing it from the slot?
Wes Welker is an excellent example of player development. He went undrafted because he was undersized and posted only average speed. Originally signed by the Chargers he was released after one game. He spent 2004 through 2006 with the Dolphins. He was about to be cut when he was abruptly traded to the Pats and the rest is history.
I need to nitpick you here. The Dolphins weren't about to cut him. Welker was a restricted free agent, and the Dolphins placed a second rounder tender on him. The Patriots traded them a second and a seventh for Welker. Miami did value Welker and would have kept him around otherwise. He was just beginning to flourish for them.
