Tet McMillan's NFL comp is Tee Higgins... Like Will Campbell, many "experts" feel #4 is too high for either player.. I'm not so sure. What is the expectation for a top 5 pick? I would say it's at the least, a difference maker with a high chance of a second contract. So if Will ends up a top 10-ish LT, if Tet is a 80+ catch, 1100 yard, 8 TD guy... I'm fine with either at #4.
Specifically with Will, if he's a very good LT and solidifies that position for like 8+ years it's a great pick.
These people need to justify their salaries. So they're not going to say "anyone who's a quality 10 year starter is a good pick, even in the top 10", because that won't drive ratings/clicks/views. But that's the reality of the draft. Of course you want to draft a generational player, but the odds are always against that, even in years where the draft is supposed to be stacked, and those "experts" know that.
And this year is considered to be a very down year at the top, so "it's too high for that player" at the very top of the draft is even less meaningful this season than most.
