Why stop there? Just trade Neal for Mackinnon while you're at it

Can't see Vegas having any interest in this

we have enough Winger depth as is

sure there will be plenty of suitors for Fleury with retained salary, and Vegas could reasonably retain 50%

He's not a cap dump

If Vegas took Neal back they wouldn’t retain on fleury

They really can’t hold onto 50% for the next two years. That’s 3.5 in dead cap that they’ll need for contracts and a backup goalie. Vegas would explore moving jt all or about 1M RET

They can definitely afford to retain 50% (not saying its ideal, but they can)

it's gonna cost them Sastny, but he is also the easiest piece to replace with Glass.

they don't have any big contracts coming up in the next 2 years

Whitecloud, Roy, Glass and Hague are all locked up cheap for 2 yrs as well as pretty much all of their core.

Well that is just preposterous. MacKinnon would likely not be satisfied with a 3C role with the Oil, although I suppose this would check the box for our need for a centre that can drive a line at even strength. 
I am not that clever, this was Bob Stauffer’s (Edmonton color guy, big-time-homer) idea. He was on the radio suggesting it. I am not sure why he thinks Vegas retains here, but if the deal was straight up; and Edmonton thinks Fleury has anything left in the tank, this could work. I think it might me a bit harder to move $ 7 million goalie that appears to be declining this year than you might think.

They won't need to retain half but they could. They have no one big to sign apart from Lehner and that money would be there. They might need a defenseman but unless they go after Pietrangelo there's no one they need to be spending the big money on. They have some forwards they will probably look at trading as well for more space.

Glass, Dugan, Elvenes all need to get their shots next two seasons. Hague and Coghlan will get their chances on defense. Stastny is off the books next season and Tatar retention. Krebs may be ready at that point.

Neal is a non-starter they don't take that contract at all.

They would just retain 30% and be done with it. Fleury at 4.9 is an asset to other teams. He's had a solid playoffs every time he's been called on and still looks good, Vegas management just apparently chose the younger guy.

No way they take an extra year of Neal, it messes up their entire structure for when Glass, Hague, Dugan, Elvenes, Roy and Whitecloud would be due raises. Not all will get them but a few will.

Vegas refused to sign Neal two years ago for more than 4x4, they especially don't do an enormous favor to a division foe and give them a useful player for a useless one signed a year longer.

You actually think Vegas will take back the Neal contract, and retain on MAF and send him to Edmonton? That's silly.

Vegas won't dole out 2-3m for bottom defenders, backups and bottom 6 guys. They'll also go with 22 or possibly even 21 players for the season opening roster.
