The issue for rookie WRs, that is VERY DIFFICULT to see before they play an actual regular season NFL down is, their adjustment to the NFL speed and how they can grasp/learn an NFL offenseAgree. And the problem is that guys like Justin Jefferson, Jamarr Chase, and Deebo Samuel only represent three guys, three picks. Where someone is drafted is not a consistently reliable indicator of how they'll perform. I don't expect Gluten to find a guy like one of these, but I do expect a top 10, maybe top 20 pick will be an impact player at some point in year one. But even the word "impact" is subjective.
I expect a pick from 1 to 20 will start day one. That doesn't apply to some QBs who may sit behind a veteran for a year or two. Gluten will come through for the WR group, the team and the fans.
The NFL isn't the same where you can win on talent alone, unless you are a transcendent talent like the guys mentioned before. But even then, it's hard to gauge "how fast" they will be or "how smart/crisp/precise" their route running will be and ability to beat zones, etc
It's pretty much IMPOSSIBLE to know lol
Otherwise, Justin Jefferson, Higgins, Samuel, etc are all Top 5 picks in their draft classes easy...
Even Randy Moss and Davante weren't top 5 picks...
So it's basically impossible to tell/know
