If Kelce is the most complete player at this position, Demetrius Harris is certainly the most intriguing. The former basketball player offers a level of flexibility and athleticism the other options at tight end simply cannot match.
Those are attributes that have become key characteristics of the modern, "move" tight end. The type of hybrid weapon who can outrun linebackers, overpower defensive backs and leap above any kind of coverage, expands the whole playbook for an offense.
The Chiefs don't have that kind of versatility among their other receiving targets. Harris faces a tough battle making that level of impact, but the potential is definitely there.
He has been an impressive figure during OTAs, per ESPN.com scribe Adam Teicher:
Tight end Demetrius Harris continued to make some impressive catches. He took an interception away from Derrick Johnson with a nice grab and later caught an Ales Smith pass that was low and behind him.
Offensive coordinator Doug Pederson is also encouraged by Harris' natural ability, per Dave Skretta of KCChiefs.com: "The emergence of Demetrius Harris, he's a tremendous talent. He mixes in there with those guys."
What Harris has is the raw tools of a natural playmaker. The next step is mastering the nuances of the position, as well as refining his technique. So far at least, Harris is making a good start in that area.
If Chiefs fans will permit this writer to use AFC West rival the Denver Broncos as an example of Harris' potential, then consider the case of Julius Thomas. Another tight end with a basketball background, Thomas had caught only one pass in two seasons, before hauling in 65 in 2013.
Now there's no guarantee Harris makes anywhere close to that impact, or even survives final roster cuts. But his natural move skills and ability to stretch the middle zones are something Reid and Pederson must explore fully this offseason.
