Having a two-way TE that can block AND catch at a high level helps. Kelce and Noah Gray fit into this mold.
As for SF: Kittle fits this mold as well. Kyle Juszczyk can line up across the formation.
Patriots: look at Gronk and pre-conviction Hernandez.
Tampa (Brady) - you had Gronk and Cameron Brate. Brate isn't a world beater but was good enough.
While this might not apply to KC, the other teams listed here had WRs that were decent blockers.
