Will Gates be back in SD next year?
Yes, unless he wants to retire, which I doubt. They certainly aren't going to cut or trade him.
I read somewhere that Gates will be 35 next summer (oldest TE) and is due $5.9 mil in the last year of contract. Hasn't exactly been a picture of health throughout his career. Green is younger and cheaper and it may be in SD's best interest to part ways with Gates after this season. No idea if that will come to fruition or not but it's plausible. That could mean Sunday is last time Gates takes the home field as a Charger in reg season game. A little extra strength to the argument for starting him this week, IMO.
Reposting from the Ladarius Green thread:
Gates continues to be Rivers' primary TE target, and is second on the team with 77 targets this season. Here is where Gates currently ranks among NFL TEs this season: #6 in targets, #6T in receptions, #8 in receiving yards, #14 in YAC, #3T (with Graham) in TDs, #4 in drop rate (minimum 30 targets). Bottom line: he has been great.
I see people speculating that the Chargers will part ways with Gates after this season. Unless Gates decides to retire this offseason, IMO there is no question he will be back. It may require him to restructure, but, if so, that will happen. IMO he will be back until he decides not to come back or until he proves in an extended period of playing time that he can no longer get it done.
