There are very few, if any te's who do both. Kittles is about the only one, but Kelce is the model in todays nfl imo. Hell Evan Engram was a huge factor in Jacksonville. I really like Akins even though he's an older guy by age, but he has movement and run after skills that are top end. I'm not saying pass on a te, I just don't see a te, Mayer included who can dictate coverage and punish defense. I've said before , a te who can just be a seam route guy and not a guy who can keep safeties and lbs inside and still win isn't as valuable high. Mayer reminds me of the former Vikings te from ND taken high a few years back. Not a bad player, but not as good as his spot warranted. A really good offensive mind can take an Owen Daniels, Kittles, Andrews, type guys and translate into a force.
