If Ottawa moves out Legwand, Neil, Greening, Anderson, Phillips, Michalek, all these redundant players with huge contracts that are easily replaceable, they'll have a ton of cap space.
anderson is not redundant, atleast not until lehner proves he can fully take over as a number 1 goalie (and hopefully improves his rebound control)
that being said if someone offered up a massive overpayment for him i would take it and run
out of the rest of the players you listed, the only player we will have a hard time trading is greening (unless some gm has a stupid moment). Phillips and Neil are not going anywhere because lets face it. Michalek and Legwand could potentially be dealt for picks at this TD or in the offseason. I also think Weircioch is going to be traded soon and Zack smith should be traded before other teams catch on that he is our next greening
so with that being said
Clarke MacArthur ($4.650m) / Kyle Turris ($3.500m) / Bobby Ryan ($7.250m)
Mike Hoffman ($2.500m) / Mika Zibanejad ($4.000m) /????????
Alex Chiasson ($2.250m) / Curtis Lazar ($0.894m) / Mark Stone ($2.250m)
Matt Peumpel ($0.863m) / JG Pageau ($1.250m) / Chris Neil ($1.900m)
Colin Greening ($2.650m)
DEFENSEMEN
?????????/ Erik Karlsson ($6.500m)
Jared Cowen ($3.100m) / Cody Ceci ($0.894m)
Mark Borowiecki ($1.100m) /Eric Gryba ($1.250m)
Chris Phillips ($2.500m)
GOALTENDERS
Craig Anderson ($4.200m)
Robin Lehner ($2.225m)
Cap Payroll:$55,751,000
Gives us around 13 million/what ever gets us to the lower cap to address two holes in the lineup. On top of that we could potentially use the returns from our michalek/smith/wiercioch/legwand to try and get a cheaper solution to insert into our lineup
