The Colorado Avalanche organization did indeed just reveal the list of injured players, and it is also impressive:
"Bednar says that during the Stanley Cup playoffs, Darcy Kuemper had to go to an optometrist 2-3 times a day to re-train his eye (emphasis added, he had to go 2-3 times per day)
Other Avalanche injuries:
Val (Nichushkin) - broken foot
Burky (Burakovsky) - broken foot and thumb
Kadri - broken thumb
Girard - fractured sternum
Helm - abdominal tear" - Vic Lombardi
So we see here that, yes the Lightning were banged up, but so were several Avalanche players.
How about Valeri Nichushkin and Darcy Kuemper, two extremely important players for Colorado who were in bad shape.
