Jarry is not a good goalie. his stats may be good but that doesn't make him good. I remember seeing him always out of position and falling/spinnign around every time I watched a pens game
Dont get me wrong I love Flower, but no this is not the move that wins the Penguins the cup. Despite your eye test of Jarry he actually is a good goalie, the only cause for concern is when will his yearly injury happen.
Fleury will be retired in a year or 2. Jarry may not be great but not bad enough to give a first to unload him. Maybe Pens trade Jarry before end of contract but it's not happening soon
