To a certain extent this shouldn't be a surprise and why when they compare draft status with stars, you get such as discrepancy on OL. Example:
Player #1 - 6' 6" 330 lbs. Shorter arms, but called "powerful" High 4-star. Why? Size. Dominates kids, but of course experts say he can "clean some things up". Gets to college and gets early burn due to being physically "ready." Very happy with himself and PT, but also gets bumps and bruises along the way, not as much into the daily grind / technician side. Draft day: 6'6" 320 lbs. Lots of tape, some good, some bad.
Player #2 - 6' 6" 250 lbs. Long arms High 2-star. Why? Size. Gets to college and rides the pine. During that time though he puts on weight the right way and gets stronger functionally to his position. Grinds hard, gets hungry, takes coaching. Doesn't play much to year 3 or 4, but now has been coached up and only has good habits. Draft day: 6'4" 310 lbs. Less tape but you see the coaching and maturation.
Who doesn't want the guy on the upswing?
Not saying what our coaches are doing with this year's OL recruits will translate, but if we had the luxury of development (which unfortunately we don't), this is a good strategy. That's why we need another potential grad transfer. Current players get a little more time to master, and 2019 recruits get another year too.
