Didn't you use to preach that "you're only as strong as your weakest link"?
Leafs aren't losing games by being outplayed, outshot and not scoring regularly, because of depth players playing < 10 minutes a night.
Mark Fraser and Jared Smithson or Colton Orr are not losing the Leafs games and the reason for the team struggles and getting dominated regularly by opponents, despite being the weakest links on the team.
When a team is struggling offensively and breaking down defensively its not a depth player issue in play here but rather your star players not carrying the load that they're required to.
Kessel had 2 ES points and only 1 assist in 13 games in November with Leafs losing 9 of them. Not sure how that is the weakest links on the team fault? Leafs have the lowest scoring Defense core in the NHL, so again it doesn't appear Mark Fraser is the reason whey Phaneuf, Gardiner, Rielly and Franson are not contributing offensively.
