What makes the trade that much better is that Timmins, who is only 24 years old, is a restricted free agent at the end of this season. This means the Leafs will have exclusive negotiating rights with him come this summer. Kyle Dubas stated after the trade was completed that he believes Timmins can help now, but that the deal was also made with the future in mind.
Per Dubas, the immediate plan for Timmins is to have him meet the team in Minnesota. From there, he'll skate with the team and then Dubas will leave the decision on when he plays with the coaching staff. It's not all that far-fetched to suggest that, given the current blueline situation, Timmins could draw in for the Leafs immediately. If he doesn't play against Minnesota on Friday, his next opportunity to make his Leafs debut would be Saturday in Pittsburgh.
