A right-shot defenceman who will be a UFA at the end of the season, Mayfield carries a cap hit of $1.45M. The Leafs currently have $4.4M in cap space due to
Matt Murray being placed on LTIR, however, Kyle Dubas said he expects Murray to be back sooner rather than later which would put the Leafs very tight to the cap. Essentially, it confirms that any deal the Leafs make now will be money in, money out as Johnston mentioned and with a number of pending UFAs on their roster, the Leafs could certainly swap one pending UFA for another.
