Tre' McKitty
Tre' McKitty was a third round pick by the Los Angeles Chargers in the 2021 NFL Draft and would start 12 games over his first two years. However, he didn't make much of an impact with only 16 career receptions and 117 receiving yards while still looking for his first career NFL touchdown.
McKitty would be released during last season and joined the Bills' practice squad. He would re-sign with the team shortly after the season on a reserve/future contract but the tight end position is probably one of the more crowded currently on the roster.
The Bills are almost guaranteed to go into the season with three tight ends and those three will be Dalton Kincaid, Dawson Knox, and Quintin Morris which was the three primary tight ends from last year. McKitty certainly has a good chance to remain with the Bills on their practice squad but would be a big surprise if he made the 53-man roster.
