I disagree to an extent.What did Clifford do to suggest he should be playing? He's been awful for awhile. It isn't about gifting, it's also about the process and development.
Leafs and Keefe are capable of making mistakes. I think this is one of them, even if it feels pretty minor. They've already thrown away really good depth players for nothing... let's not keep making the same mistakes in favour of bad veterans.
While I agree that it's a minor move, Semyonov has been absolutely mediocre in his limited time. Amadio and Brooks are both also fringe players who didn't being much of anything to the table.
Clifford's experience and style of play allow him to enter the lineup and immediately make an impact, as small as it may be. What he may lack in terms of skill can be made up with his skating and physicality. He's being given an opportunity to show what he can bring tonight and I hope he makes the most of it.
Having a physical vet like Clifford as our 7th bottom 6 forward can be beneficial and impactful.
