Now, while Jordan's strengths may quickly entice, we shouldn't go overboard with them either. 
To start, age could be a very important factor in Jordan's draft stock decline. Despite my efforts to find his exact age on the internet, I couldn't find it, but with 6 seasons spent in college football, he must be in the older range of prospects, which could directly lead to a drop in his value. 

In addition to his age, I noticed that Jordan often played too high when starting from a 2-point stance, as was often the case this year in Colorado's system where he played OLB EDGE. It's a shame because when he starts in a 3-point stance (the classic DE stance), he often manages to stay low. This was actually one of his strengths that I noted last year when he played at Arkansas.

Domineck sometimes struggles to stay under control, especially when he's in a Power Rush situation. Indeed, he tends to dive too much in order to physically beat his opponent. The problem that arises is that Jordan ends up completely off balance, so all it takes for the blocker is to pivot his shoulders and transfer force to make Jordan collapse to the ground. The same happens when Jordan has to attack a gap; again, he has a strong tendency to dive straight into the gap without considering what will happen next.

Another weakness of Jordan is his tendency to get too close to his opponent at times. It's not uncommon to see him sticking his chest to the opposing offensive lineman during his takeoff, thus making the task more difficult for himself. From this position, unless you have enormous strength, and spoiler alert, that's not the case for Jordan, it's nearly impossible to create separation. Once again, I find it unfortunate considering he is capable of developing a nice punch.

One point that really frustrates me about Jordan, because in my opinion it's something that can easily be corrected and should have been addressed long ago, is that when Jordan plays, he works too much head-on against his opponent. He needs to learn to work on just one side or one quarter of the player to make his life easier. What I mean by this is that instead of facing his opponent head-on, it's much easier to work on his outside shoulder, which makes it easier to unbalance the opposing player. If players much stronger than Jordan struggle to beat offensive linemen with power, there's a reason for it; he absolutely must work smarter. The time he sometimes wastes battling with his opponent is significant, and what often results is a missed opportunity.
Moreover, to stay on the same subject, Jordan often becomes ineffective rather quickly when faced with a double team situation. When I study players' tapes, I expect to see at least some ability to fight back, and that's clearly not the case with Jordan. If he finds himself in a double team situation, he gets taken for a ride, partly due to the previous point. Since Jordan often decides to attack his opponent head-on, inevitably when a second player comes to assist the first, they arrive on one of Jordan's shoulders and can quickly unbalance him. And as you're beginning to understand now, once a player is off balance, it's game over.

Despite a significant increase in the number of tackles on his stat sheet, it must be acknowledged that Jordan's tackling technique needs improvement. Too often, he arrives too high, and it's not uncommon to see him take poor angles, leading to missed tackles. Another area that needs work.

Finally, mental toughness will be a concern to watch closely, as it's not uncommon to see Jordan quickly lose motivation when he gets stuck in a block. He too easily accepts giving up on the play and allowing himself to be dominated. I definitely don't like to see that kind of attitude.
