Pretty sure Stetcher Holloway Ryan will all be in as well so 4 players will be sat today and again tomorrow. I don’t know if they have the cap space to bring more up?
Cap space isn't an issue anymore as the remaining cap hit of any player called up would be in the range of $8K to $12K depending on which player and Edmonton has a $178K cap space (possibly less as Gregor has suggested the numbers on CapFriendly and Puckpedia are a bit higher than the actual numbers Edmonton is working from.
I think it's at least partially due to them wanting to let Bakersfield have the best chance at moving as high as possible (could finish as high as 4th place giving them home ice for the first mini round or as low as 7th which would have to face the 2nd best team in the Pacific for the mini round). Also probably due to the fact they already have 4 available players and they know what to expect from Gagner.
Knoblach did a good job of keeping the ice time balanced on Monday, so as long as he keeps that up with all forwards being 13-16 minutes and all defense 19-21 minutes, it's fine. Especially if you dress all 4 of the available players.
That said, I thought Skinner starting Monday was them telegraphing that they would let him stay home and call up Campbell to back up one of these games and start the other. Apparently not.
