The redshirt sophomore is leaving the team.
I don't know if it's the lack of playing time even when he was the most experienced tight end on the team (which isn't saying a lot), but Chris Laye was apparently unhappy with the situation at Auburn and has decided to transfer.
Laye didn't receive much in the way of playing time during the 2015 campaign. Nor did fellow freshman Jalen Harris. Auburn didn't exactly use the TE position in 2015, which may have been part of the offensive problem. The Tigers started freshmen (either redshirt or true) at both the TE and H-Back position, and Gus went with the H-Backs in the majority of offensive sets.
