I worry that Edler might be one of those guys who looked decent one year, and then falls off a cliff the next. It happens to some players in their 30's, and he's played a ton of hockey and battled through a lot of injuries. For all we know, he may have one now. That's all you can really hang your hat on.
Because at times on this road-trip it looks like the game has just passed him by.
It may end up looking exactly like that, though it makes one wonder whether some of the time is due to long-term fatigue.
To use an analogy from other sports, when an endurance athlete overtrains his performance declines and the solution, assuming a clean athlete, is to rest. Training has to be dialed way back for some period of time or the athlete will suffer a slow decline. When athletes don't understand what has happened and try to improve through harder training it just makes things worse and can considerably prolong the time needed to get back to peak performance.
It seems to me very likely that Edler was overcooked earlier this season, then instead of being dialled back he was overcooked some more. His level of play isn't what it was earlier in the season. If he has in fact been overtrained, it's hard to see him getting the rest he needs to get back to peak performance quickly so it could well appear that the game passed him by when if his ice time had been 19-22 minutes a night he'd have been effective.
I doubt that holding him down to 19 minutes a game is going to get him back to normal very quickly at all. While it is hard to see it happening, I think
@MS has the right idea thinking in contemplating giving him the odd night off (MS suggested on a back to backs.)
One of the effects of ongoing fatigue is that the likelihood of injury goes up. I would never wish an injury on someone, but paradoxically it might be the only way, in practice, that Edler gets rested.
Even an overtired Edler still does a lot of things right, but on 24-30 minutes a night I don't think he's going to be near peak effectiveness in the long run.
It's a lot like watching Tortorella ride the twins in 2013-14. They were playing big minutes for forwards in the first half of the season while Torts desperately tried to keep the team at a playoff level. Daniel scored 35 points in 41 games before the new year, 12 points in 32 games after. Henrik also had 35 points in 41 games before he new year (27 in 28 games by the end of November,) then he had 15 points in 29 games after the new year. Both were losing effectiveness well before the new year and that effectiveness didn't come back until the next season, when after a summer to rejuvenate the twins played an average of about 2 minutes per game fewer than the previous season.
The twins were 33 years old in 2013-14.
