my comparison of the two nose/1techs remaining our board (I also believe Silvera is good, well rounded enough to play at both tackle positions, so he may help out at nose too)
Coburn- I don't see many weaknesses. Looks strong and stout, maybe not a super freak athlete for 325, but definitely above average, not a pig. Stays low, probably because he's only 6'1...I can't imagine there are 3 or 4 better 0 or 1 tech in the country. Looks like he got rid of a little bad weight junior to senior year.
Miller- Needs upper body strength imo, gets a little high at times, more so when he seems to be tired on the play to begin with...or maybe it's standing upright that makes him look tired. Basically needs upper body strength and conditioning, can see that in his tackling, and the occasional getting stood up. More of the pear shape than Coburn who's wider in the shoulders, but this kid's legs and base are huge. Very quick off the ball and in short space, struggles a little laterally, but not a total sloth. I would say he is behind Coburn, but has upside. Raw at this stage, but a lot to like. 3*, top 30 true nose if you had to put a number on it. Needs 2 years to see the field imo, but I like the take at this stage.
Occupies space, blockers= Both
First step= Miller
Strength= Coburn
Balance/hard to move= Coburn slightly, stays lower
Agility/ Lateral Pursuit/overall athlete= Coburn
Motor= slight edge Coburn, but his film was shorter, and prob didn't show plays he took off.
