Like the Leafs, the Jets are coming off an extremely disappointing playoff performance, losing in the first round against the Avalanche 4-1. Also similar to the Leafs, the Jets are looking to make changes to their existing core.
Earlier on in Ehlers' career, many compared the former 9th overall pick in the 2014 draft to the former 8th pick in that same draft, William Nylander. While Nylander has definitely surpassed him, Ehlers is a great top 6 option that has proven he can produce year after year.
The Leafs are set to offload some cap space this summer having a copious amount of UFA's, making Ehlers a valuable option if a trade can work out here. Also if the Leafs do decide to move on from superstar Mitch Marner and his almost 11 Million dollar contract, Ehlers would be a good option to replace him in the top six, and with his lower cap hit, the Leafs would have an additional ~$5M to play with.
