I don't know what the right answer is, but I think he does remain. So I voted yes.
The more this goes on... the more I feel the GM is not the issue.
The team plays the possession game in too literal of a sense and at all times... there is a time and place for it... it is not an always thing. Sometimes you have to make a non possession safe play and get back at it on the flip side.
I dunno if it is the players who are, as a group so situationally unaware they just keep doing the possession thing in the wrong moments, or if Keefe is asking them too... deep down I am pretty sure it is the former. Guess they haven't learned that lesson yet.
