yes

it really depends. he did have some signs of being okay this year but hes just been injured, they might be one or two gms that would pay something small

imo he has positive value still. he came back strong after his second injury, only to get injured once again. if he's fine after his last injury then he's positive value, otherwise no he has negative value
feel like a team low on goalies (ARZ, NJD come to mind) might trade something minimal for him

Mrazek is the Leafs starting goalie next season.

Could probably easily deal him for a player with similar term and cap hit.

Really depends on how the backup goalie market in UFA ends up

He's a very special kind of negative value - a player coming off a really unfortunate season (.888 SV%, 3.34 GAA, -9.6 GSAA in only 18 starts) with a somewhat significant cap hit ($3.8M) on a backloaded contract (he gets paid $4.2M & $4.4M the last 2 years of the contract).

You're going to have to pay to have someone take him off your hands - the trick is going to be finding a bad team, that needs a goalie, that isn't a floor team.

BAD TEAMS (for the sake of this, everyone who finished with a less than .500 points percentage):
Buffalo
Ottawa
Detroit
Montreal
Columbus
New Jersey
Philadelphia
Chicago
Arizona
San Jose
Anaheim
Seattle

From that list we can say the following teams will not be in the market for a goalie: Seattle (Grubauer & Driedger signed next year), Anaheim (Gibson), SJ (Reimer/Hill/Kahkonen), Columbus (Korpisalo/Merzlikins), Montreal (Price/Allen), Ottawa (Forsberg/Murray). We can knock off Arizona as a floor team that would want to avoid paying more cash than the cap hit, and we can most likely knock Detroit off because of lingering bad blood on both sides.

That leaves: Buffalo, New Jersey, Philadelphia, Chicago. New Jersey probably passes because they do have enough guys signed in the system, even if they were a goalie graveyard this season.

Buffalo could make sense if they want a seat warmer until one of the Portillo/Levi/UPL is ready to take over the starter's job, but I also feel like they'd make Toronto pay dearly for help.
Philadelphia needs someone to backup Carter Hart, but they don't really have a ton of cap space this summer ($5.1M) and I can't see them using 3/4 of them on a mediocre backup for Carter Hart.

Chicago is going nowhere, will have the cap space, doesn't have any goalie knocking down the door, and is probably a couple years from contending. I'd have Toronto send over a prospect list and pick someone that's 2-3 years away and have them send them with Mrazek for "future considerations".

To be honest, his value is relatively low. The Leafs don't have to give up a 1st to get rid of him though.
He did play well in his final starts before going down with injury so his trade value does show signs of life.
But he'll probably be traded to rebuilding teams and the right price is a 3rd and 6th or 3rd + 5th for 7th coming back.
There are teams that need goaltending like Chicago and teams that need to reach the cap floor like Arizona.

Passed waivers late in the season, tells you all you need to know. If no one will take him for free, then the leafs are paying to get rid of him

Ya. Probably will cost a 3rd round pick to dump.

He has negative value.

Please bear in mind that he has always been injury prone, and has already worn out his unreliability in DET, PHI and TOR. Theres alot more reliable backups available for FAR less and no term.

You're just fooling yourself if you judge his value on his talent/ability alone and ignore his ridiculous contract and extensive injury/reliability issues
