But on Sunday the San Diego Chargers offensive lineman will face his former team for the first time, and he’s looking forward to it.
"It’s going to be exciting," he said. "I didn’t leave with any ill feelings or any angst toward that organization. They were the ones that allowed me to get my foot in the door in this league and gave me an opportunity when I went undrafted, so I’m always thankful for that.
"It will be cool to go back and see everybody. I’m still close to a lot of the guys I played with there. But obviously for 60 minutes we’ll be competitors."
The Bengals brought Robinson in as an undrafted rookie free agent in 2012. In his first two seasons in Cincinnati, Robinson started in seven games. He spent the 2014 season on Cincinnati’s practice squad before signing to San Diego’s active roster because of a rash of injuries at the center position.
Robinson, 25, was a late replacement for injured starting center Chris Watt in a win against the Baltimore Ravens last season. He again replaced an injured Watt three weeks later in a comeback win against the San Francisco 49ers and started in the season finale against the Kansas City Chiefs.
Robinson signed a two-year deal during the offseason to remain with the Chargers.
With D.J. Fluker suffering a high-ankle sprain in Week 1, Robinson could get the start against the Bengals, with Watt sliding over to play right guard.
Robinson has plenty of experience facing Cincinnati’s talented defensive front in practice, including matching up against active defensive tackles Geno Atkins and Domata Peko. And that experience should serve the Chargers well.
"I was the backup for the majority of the time I was there," Robinson said. "When you’re in that role throughout the week, you’re the one running the cards against them. So I’ve probably had as many reps against this starting defense as anybody else has. So hopefully I can help out in that way and pass along some information to some guys."
Added Watt: "He knows some stuff about the team, the players and how they play, so that will be huge to lean on him for that. I’m sure they’re going to change some of the defensive calls, because Trevor knows what he’s talking about."
