Freddy's playoff problem is sort of overblown, but at the same time it isn't. He gives up a Patrick Lalime level stinker or two during every do or die game. And Lalime himself is important to mention - he's 7th all time in playof sv%, but no one will ever remember him as a good playoff goalie because the dude just let in crippling stinkers when it mattered most.

Now this one isn't as bad, and is harsh for me to put because he played really well, but worth noting.

Obviously, he's not THE problem... look at the scoreboard, we scored a 0-1 goals in 3 out of those 4 do or die games. That's the main reason. But you can't look at that and tell me Freddy is the solution either, because he sure as shit isn't. He's basically on the very precipice of the Andy Dalton line of goaltending - being good enough to where you can get away with him being in net as long as the right pieces are around him. But the more and more we improve defensively, the less and less flattering Freddy seems to look.
