He really has to be better than Rielly off the hop. The Leafs can't gamble on a 9.25M x 4 player to maybe improve with a change of scenery, they are on the clock to be good this season. A player needs to earn a deal like that because of what it takes away from the rest of your club's budget and DK hasn't and has put himself under a magnifying glass because of it. One in three chance he is some version of expensive but okay, one in three he is better because of those tools, and then there is the chance we haven't even seen what bad Darnell looks like. A club that wants the physicality and has a well set up D with a hole to fill works but the Leafs are more in the triage stage this summer.
