While I agree with you that injuries have hampered his play throughout his tenure with Ottawa, I think his lack of dedication and appropriate training have played large part in him getting those injuries. Perhaps less with the hands, but that's a more recent pattern, and hands don't stop you from skating and overall compete level, which has always been incredibly inconsistent with Bobby.
Yes but it’s impossible to know. It’s all speculation. One thing to have in mind is that he is a skilled player, very high end skill (look at some of his goals in his career, dang), so he might have been practicing skills and shooting more than most players
Some players are just injury prone, Ryan has a very good frame and seems athletic enough but the « grinding » of the season and the style he plays eventually plays against him. I don’t think there’s much he could do about it
Concerning his skating, Ryan has never been an above average skater but he also had some injuries that hurt him in that department
His 3 first seasons in Ottawa have been fairly productive (~o.70 PPG all 3 years) but it could have even been better with better endurance and avoiding injuries. This year and last have been plagued by constant injuries; hard to find a solution about it, only luck could get him out of this.
