John has the size you look for in a defensive tackle for the NFL. He has long arms to help him get off blocks and make tackles at the line of scrimmage. He is a beast for most offensive linemen to handle for all four quarters because of his weight and because he leans on his opponent using the weight to his advantage. He works in a three man defensive line inside and outside and is adept at taking up space. John looks like he might be quick off the line and a beast to handle on pass plays, but right now I would have to consider him a two down defensive tackle who fits a 4-3 defense for the next level.
I have many different issues for Jonathan to consider if he wants to impact at the next level. First, he needs to lose weight before the combine and forever more. Second, he needs to improve his hand usage techniques to free himself up to make more tackles at the line of scrimmage. Next, he needs to learn how to read offensive linemen and how they are blocking him because he falls for the same play over and over again, making the same mistakes and allowing himself to be blocked in the same manner which speaks to his lack of football intelligence. John is going to find out real quick that you just don't lineup across from the player in front of you and beat him because you are heavier than he is. And last, he needs to fire out into his opponent and not stand up and allow an offensive lineman to get leverage against him and move him easily out of his gap control assignment. Oh yeah, I almost forgot. He also needs to upgrade his physical stamina, including upper body strength, along with improving his mental game. Just because you can lift weights doesn't mean you are strong enough, or smart enough, to play football at a high level.
In short, John is very sloppy in every aspect of his game on the field. He has the talent, but his inability to be consistent in using that talent stems from one thing and one thing only...his weight. If he loses weight, he will be more impactful because it will be a sign that he is ready to learn and use the correct techniques to become an impact player. If he doesn't lose the weight, then what you see is what you get -- a player with too much weight to handle his own athletic ability. For me personally, I think if you can't be in shape at the college level or show the discipline to get better learning, or using, the techniques of your position, I don't think it is going to happen at the NFL level. I don't expect players the size of John to play like a small player or play better than their athletic abilities, but I do expect them to learn their craft, show improvement and keep themselves in shape for the position they are expected to play. John has first round talent and first round athletic ability, but he does not show the mental aptitude, football intelligence or physical stamina to impact at the next level unless he miraculously changes the path he is playing on right now.
