I'm not going to post the whole article, but here is what Pronman says re: Leafs and Jets specifically
2. Toronto Maple LeafsPrevious ranking: 17
The Leafs' system has skyrocketed the past 12 months, following a great 2015 draft, key trades and progression from some prospects. Mitch Marner and William Nylander are true top-flight names, and they have a lot of depth in quality prospects, many of whom are in my top 100 overall NHL prospects column.
6. Winnipeg JetsPrevious ranking: 7
The Jets system has been bubbling up the past few seasons, thanks to a great 2015 draft and acquisitions of many high-upside talents who have developed well. The Jets have a ton of dynamic, young forwards on the way up, as well as Josh Morrissey on defense and Connor Hellebuyck in goal. A lot of their top prospects are also on the cusp of pushing for NHL time, after a lot of patience shown by the organization.
