Don't sleep on Dion's ability to cover this new breed of athletic tight end. It is a huge asset to have somebody so long and fluid, not to mention having decent ball skills coming from a wr/te past.
Even though he doesn't have elite rush skills he has the athleticism to beat tackles off of the snap which is the most important trait you would look for.
My issue with Jordan will be his ability to anchor if teams run right at him. He has good bend and fights off blocks but boy is he light in the pants. My guess is he would show up at the combine 6'6 245 but still could use another 10-15 lbs of good weight to hold up.
