Maybe take a minute and watch those HUDL highlights again?
If there was one thing that the film demonstrated to me, it was "grit" playing on the line of scrimmage: there's that mean streak you want to see from an inline tight end. The very first highlight has Miles blocking the opposing defensive end 25+ yards downfield. There's another couple of clips in that video showing the same.
In other blocking highlights he's sealing the ends as well as any coach could dream of. Without counting I'd say more than a half of a dozen demonstrate such.
There's a few of him playing along the defensive line: he played both OL and DL in high school (from a smaller high school classification.)
There's a few things that jumped out to me.
- A JUCO with four to play three. The SEC requires graduation from JUCO to be eligible. We normally see these guys with, at the most, two years to contribute. He's well ahead of the game, academically.
- I love seeing guys on the line with basketball backgrounds: their footwork tends to better. It never hurts having a BB guy because they also tend to have good hands. Here we have a guy who can block, but is still a receiving threat. OJ Howard couldn't offer than his first few years.
- His coach pointed out he's competing against DE's who carry multiple P5 offers and he's doing more than handling his own: daily.
- He's 6'5"/6'6" and currently around 250 lbs. His injury last year held him back, physically, but he's gained "a lot of muscle mass" in their winter workouts. I can easily see him hitting the 285-290 mark. Size wise, and athletically, that's prototypical for an inline TE.
