Pro Football Focus has a neat story up looking at what percentage of passes from a quarterback to a receiver were "on target". Kansas City Chiefs TE Travis Kelce ranks very well in this.
In fact, Kelce is ranked No. 1 on this list with 89 percent of his throws on target. That's a credit to Chiefs QB Alex Smith who was one of the most accurate passers last season. It also speaks to the shorter passes that Smith tends to throw. Those shorter passes led to Kelce having over 500 of his 862 yards after the catch.
PFF also makes this observation:
Although we can't count on Kelce continuing to dominate after the catch, it's worth noting that Brent Celek was annually near the "RAC" leaderboard when playing under Andy Reid. Either way, Kelce will surely remain efficient as long as Smith is under center.
So maybe it's reasonable to expect Kelce to have another big RAC year.
