I think he stays.
Time in the juniors will do him no good. It's a safe bet that we will have more injuries this year, and he can increase his ice time then. He is young and still getting over his injury. If Salo and Mitchell are both back, sit him next game, see how he does with a bit of rest (and a couple practices at home) and decide later. the first month was almost all on the road, and I think the travell might have gotten to him a bit... you never know..
I would think even just being around some of the leadership we have will be good for him and will help his development more than excelling in the juniors. If he is still getting less than 10 minutes a night at christmas time, loan him to The World Junior team where he can log a ton of minutes in presure games. I just think that at his level, he is wasted at the junior level.
Edler was called up to fill the hole caused by excesive injuries. keep him up for one more game to ease Mitchell and Salo back into the lineup and then make a decision on Luc for saturday.
Now, if he could be sent to the Moose, it would be a different story...
