Kelce is a major part of Kansas City's trio of weapons of him, receiver Tyreek Hill and rookie sensation Kareem Hunt. The tight end's size and athleticism puts him squarely in the conversation for the NFL's best tight end, and also makes him one of the league's most dangerous targets. The Chiefs' offense is substantially better with Kelce than without, but if he's forced out in Week 6, Alex Smith will have Demetrius Harris and Ross Travis in Kelce's place.
