Having taken a look at whether the Leafs should trade their bevy of forwards (including those on expiring, short term, or long term deals), lets now discuss one of the crown jewels of the Leafs rebuild in 21 year old defenseman, Morgan Rielly.
History
Rielly's entire NHL career has been with the Leafs, who drafted him (to mixed reaction) with the 5th pick in the 2012 NHL Entry Draft. The first round in that draft was dominated by defensemen. Despite being picked 5th overall, Rielly was the 3rd defenseman off the board, and would be followed by 9 more in the first round.
