He will be making 7.5 million next year. Ryan in my mind suffers from 2 big flaws 1. His skating is getting worse each year and 2. Motivation. He came back last year from injury right before the playoffs and went on a tear. However he missed a lot of games last year before the playoffs (I believe he only played 62 regular season games total) and was rested and avoided the grind of a full season.
His skating actually looked pretty good this year. A few weeks off and you lose your synch, get a bit out of "game shape" and then your confidence get shattered as you might be playing to not getting hurt again.
Since Ottawa got him, Ryan has been dynamite everytime he was healthy, but he just can't catch a break. He is unfortunately injury prone...

And this season he started with 6 points in 8 games (playing very well) but then again got injured. We have little info on players injuries and most of the time they play through it and it makes them ineffective (think about Turris in 2015-16). It must be very hard to stay productive in injured plagued seasons. It's reminiscent of Marian Gaborik, pretty darn good players who eventually ran into too many injuries.
Basically, Ryan was a ~70 pts player looking at his first 42-60 games in his first 3 seasons with Ottawa, but couldn't maintain his paces all season because of injuries and physical endurance. Sens luck I guess as they get screwed once again by injuries, because I believe they would have a close to elite player if he was able to stay injury free.
