The Los Angeles Chargers have made some substantial changes over the past couple of years. However, they officially closed the chapter on an era with their decision not to bring back tight end Antonio Gates.

The departure of Gates deals a blow to those fans who have followed him throughout his illustrious career. According to Ricky Henne of the team's official website, no one is sadder to see him go than quarterback Philip Rivers:

“That is special,” Rivers said. “Speaking from a selfish standpoint, I don’t know where I’d be without him. If he hadn’t been here for 14 years, I don’t know what my career is like. You’re talking about a pretty unique opportunity to be paired with the best tight end who has more touchdowns than anybody. And then I’m able to share in many of them. It’s awesome, and that part is important. It’s great to have something we can share together. That part is cool and special to both of us. When you see the names like Young and Rice, Peyton and Marvin, and you see Rivers and Gates; that is special.”

It goes without saying that Rivers and Gates were one of the most formidable passing duos in NFL history. Their 87 touchdowns put them behind only San Francisco 49ers legends Steve Young and Jerry Rice more most combined touchdowns. Much like their predecessors, each player elevated the other's game.

Gates was largely seen as a project player after distinguished basketball career at Kent State. However, the chargers recognized his potential and signed him as an undrafted free agent. He enjoyed modest production up until the arrival of Rivers and would ultimately help kickstart the revolution of basketball players transitioning to football. More importantly, Gates is perhaps the best to ever play the tight end position. As gifted as he was, it likely does not happen if a gunslinger like Rivers was not under center.
