Matt Ryan’s offseasons have mostly resembled an ocean of calmness in past years.

For the Falcons quarterback, who offers an air of unflappability, little appears to distract him from his stated goal of winning football games.

This offseason, a couple of factors — some under his control, some not — have derailed him a bit. Ryan being Ryan, they are mostly small ripples but at least a couple could threaten to gain momentum and transform themselves into thornier issues.

The first was the shoulder injury that he suffered in the NFC Championship Game against the San Francisco 49ers. On Tuesday, as Ryan met with the media to kick off the start of the team’s offseason team activities, Ryan explained how it took him about seven or eight weeks to rehab the injury to his left (non-throwing) shoulder, which did not require surgery. Last year, much ado was made of how Ryan spent the offseason strengthening himself and his arm. This year, from the sounds of it, rehabbing his shoulder prevented him following a similar regimen.

“In this case, this one required a lot of rehab,” Ryan said of the injury. “Usually, I take some time immediately following the season to get out of here and to take some time away from here. With the situation I was in at the end of the season, I was here for six or seven weeks, something like that before I even took a week to kind of get away from here. That’s just part of how it goes.

“It’s one of those things where, it changed a little bit, but after I got through those seven or eight weeks I was able to start training and start to get back into shape, and do the things I wanted to do.”

The next issue also could potentially affect Ryan’s health: That of significant changeover in the offensive line that protects him. Long-time veteran center Todd McClure was forced into retirement and former Pro-Bowl right tackle Tyson Clabo was cut, leaving that unit in somewhat of a state of flux and uncertainty.

“It’s inevitable,” Ryan said. “When you play in this league there are going to be changes around you. That’s just part of the business. I don’t like to see anybody go. I loved playing with Todd. He taught me so much, helped me out so much. I loved playing with Tyson Clabo. I thought Tyson was exactly what you want from an offensive lineman, tough-nosed, smart player, physical, relentless, and a great teammate. It’s tough. You don’t want to see those guys go, but that’s the nature of the sport and the business that we’re in.”
