Beyond the fact that Gronkowski has 15 more career touchdowns than Kelce (in 32 fewer games played), Gronkowski held court as arguably the best blocking tight end in the league during his prime — a key role that Kelce has not usually been assigned in Kansas City’s offense.

Rob Gronkowski is widely considered to be among the greatest tight ends in NFL history. The four-time Super Bowl champion played 11 seasons, finishing with 9,286 receiving yards and 92 touchdowns on 621 receptions. He hauled in an additional 98 passes for 1,389 yards and 15 touchdowns in 22 postseason games.

Rob Gronkowski was much more involved in the blocking game than Travis Kelce is with Kansas City, and that's just the way he likes it.
