Legendary Los Angeles Chargers tight end Antonio Gates announced his retirement from the NFL on Tuesday, ending a remarkable 16-year career.

Afterward, Chargers wide receiver Keenan Allen paid homage to Gates on Twitter:

“Man I remember it like it was yesterday,” wrote Allen. “Walking into the huddle for the first time, seeing Antonio, Phil, Ryan Matthews and just saying damn I’m here. But the way you embraced me and taught me the ropes was special for me. Just to hang around you and hear you talk was special. You Always had that swagger and confidence that couldn’t be touched and I always loved that about you. The way you approach the game/practice everyday was special. Showed me what it meant to be a PRO! What a start to your life and I hope your next chapter is even better big bro!”

Gates did not play at all in 2019, but Allen spent six seasons as Gates' teammate between 2013 and 2018.

Gates' journey to the NFL is certainly an interesting one.

The Kent State product did not play collegiate football, instead playing basketball. However, Gates did not make it to the NBA, and due to his size and athleticism, the Chargers tried him out at tight end in 2003.

Gates ended up being a smashing success, making the Pro Bowl and earning a First-Team All-Pro selection as soon as his second season.

From 2004 through 2011, Gates made eight straight Pro Bowl appearances, also notching First-Team All-Pro honors three consecutive years between 2004 and 2006.

Gates logged over 1,000 receiving yards twice in his NFL tenure, with his career-high of 1,157 coming in 2009.
