The Chiefs would like to use a lot of two-tight end formations. They planned to do more of that last season, but Travis Kelce and Tony Moeaki missed all season and Anthony Fasano missed half of it, so they were limited in what they could do there. You mentioned Demetrius Harris and he might help. But the guy who would make a two-tight end formation work for the Chiefs is Kelce. He's 260 pounds but is also a deep threat. If he's healthy, I could see the Chiefs using a lot of two tight ends. The Chiefs got 53 catches from their tight ends last season. That number needs to increase greatly this season.
