Sheldon Keefe pulls Ilya Samsonov from the net in Game 4.

Toronto Maple Leafs head coach Sheldon Keefe has seen enough.

After giving goaltender Ilya Samsonov full control of the net through the better part of 4 playoff games, Keefe has pulled the trigger on a goaltending change to start the third period.

There are two reasons Keefe would make this move, both of which paint a very different picture.

The first and most obvious is that Keefe may simply not be satisfied with the performance he has received from Samsonov through the better part of 4 games and has decided to give Joseph Woll the reigns in the hopes of getting the Maple Leafs back into their opening round Stanley Cup playoff series against the Boston Bruins.

It could also be that Keefe is merely looking to rest Samsonov in the third period given that the Bruins had established a commanding 3-0 lead, with Keefe perhaps wishing to preserve Samsonov for Game 5 which will be an elimination game should Boston hold their lead to close out Game 4.

Samsonov had an up and down season for the Maple Leafs and he certainly hasn't stolen any games in this series, recording a 3.05 goals against average and a .895 save percentage. His numbers against the Bruins in Game 4 weren't any better, with Samsonov stopping just 14 of the 17 shots he faced on his way to a .824 save percentage before being pulled after the second period.

Should Woll prove more effective in the third period, Keefe will have a decision on his hands heading into a must-win Game 5.
