I agree, except I'm not a fan of Hunter Long. I felt he played very soft for his size, lacks aggression. His explosion at the beginning of a route was underwhelming to me as well. IMHO he wont survive in the NFL if he doesn't fix at least one of those two things. If you can break quickly, cool you can create seperation...if you can box out and play aggressively you can over work the person in front of you. If you have neither of those traits, you're destined to ride pine or be out of the league.
I also didn't cover how much it pained me to watch him as a blocker.
I was glad to see the write up hit on all 3 of those points about him though. He has potential, it's up to him if he fixes his game for the next level.
