If Murray didn't become so injury-prone, it would have been him easily but he has literally been the most injury-prone NHL player in the last 5+ years... it's crazy that he still gets cleared to play (particularly with several concussions)
Murray has some history to overcome as he prepares for what would be his third Stanley Cup playoff run.

So this isn't new, look what was said in there :
The biggest question coming into the 2017-18 season about Matt Murray had to do with his ability to stay healthy.
5 years later and it's still the same question
In that article, it also shows that between 2015-16 and 2017-18, Cam Talbot only had 1 injury while Murray had 7
Murray can still be good when healthy (and has been for stretches in Ottawa), but it doesn't happen nearly enough. This is why it is a gigantic gamble by Dubas. He is gambling on Murray staying relatively healthy for the next 2 seasons.
