Hey, Sharks fan here. From all I know Jones is at least a decent guy. Decent goalie, though, well...
He did have the one postseason when we went to the Finals where he was frequently the best player on the ice on either team. So, either he auctioned his soul for cheap and got 1 playoff run out of it, or there's a good goalie in there SOMEWHERE. Just nowhere near the surface these days, unfortunately.
BTW, here on HF, people frequently took to calling him Jon3s, since he *always* seemed to let in 3 goals, whether he was in there all game or in there for 10 minutes. Best hope I can give you is either a) your goalie coach can fix him, or b) you play him very, very seldom. Because if you do....
