"The difficulty of making a trade post July 1st is now you've got a lot of teams right now that have spent their money, spent time putting together their rosters. They've allowed development camps to play out, now they're looking at the rest of the crop of free agents," said Colaiacovo on TSN's 'First Up' on Wednesday.
"We're going to see PTO season coming up here soon... Anybody that believes a big trade that the Maple Leafs could potentially make becomes even harder now for two reasons. The number one reason why this trade was always going to be hard cause a guy like Mitch Marner has a no-trade clause... The number two obstacle is any team that the player would potentially want to go to, they have to have the cap space and they have to have the assets the Leafs are looking for.
