As per Frank Seravalli of TSN, the Leafs are making another depth defence acquisition.

Gravel is a big tweener AHL/NHL defenceman, 27 years old, and he shoots left, if you were wondering. Nothing about him screams that he’s expected to be an NHL player, although the topsy-turvy state of the Leafs’ defence makes it hard to rule anything out authoritatively. Still, the most likely result is that he provides some veteran solidity to a Marlies’ defence group that is poised to lose both Vincent Loverde (to AHL Hartford) and Calle Rosen (to the big club) next season.

If he does wind up playing NHL minutes, well, he can do it and not implode, we figure:

In short, he doesn’t answer any big questions, but this looks like one of the low-level moves you make to keep your organization rolling. Cheers to Kyle Dubas and, more probably, Lawrence Gilman.
