There are two players from their class that I personally watched quite a bit, one that I didn't like and one that I really did.
I think Justin Jefferson is the most overrated prospect from this class. He played in the most talented offense in college football and was protected by scheme more than any other player in the system. He's got fantastic hands and ball skills, but otherwise he was not a plus separator and did not have to deal with press. He accumulated a ton of his production by sitting in spots against zone looks, and a lot of the single coverage he faced was against 3rd corners, safeties, and even linebackers. The Vikings use less 11 personnel than literally anyone else in the league, so Jefferson will undoubtedly have to prove himself playing on the line against top NFL cornerbacks. He could certainly develop and has the physical tools to do so, but I also think there's a strong chance that he disappoints when taken out of that cushy college role.
I have no idea what they're trying to do at WR. Their top four guys all operate best out of the slot, and they hardly ever play 11. I think the loss of Diggs is going to hurt that offense a lot more than people realize. Jefferson isn't even close to a replacement. He's actually far more similar to the receiver they still have: Adam Thielen.
Cleveland, on the other hand, is a guy I really liked. He has elite traits as a LT prospect. I personally thought he was more developed than he got credit for. He played almost all of 2019 through a turf toe injury, but was more than holding his own against FSU to start the season (his injury happened late in that game). He's ideally suited to their offense. He may need a year, but I fear they probably found a good LT for the foreseeable future. And while athleticism =/= ability, tackles with his metrics have a really high hit rate.
