That's kind of the thing... I don't see this as a bottom 10 team, not a lock for one of the worst in the league anyway. On the cusp? Maybe, but looking at another non-top 3 pick.
If the Leafs were looking to give themselves a real shot at a high pick they would need to move out Phaneuf, Bernier, and Bozak. Say what you will about those players, but they belong in the NHL and will only win you games while possibly not being part of the team in 3-5 years.
So the ideal is not to tank a la Buffalo but not shoot themselves in the foot by icing a lineup you know won't contend but has "decent" players that will keep the ship from going under in the short term but who would not be part of the Leafs' long term plans/choose to move on soon anyway.
That's kind of how the poor Leafs teams of the past few years have been and there's not much sense repeating history. That is if the Leafs intend to actually rebuild. They might have a "hybrid rebuild" in mind and be thinking playoffs next season if at all possible (wait, wasn't that how Burke drew it up?).
I would say Phaneuf is the guy you prioritize moving though. I like him overall and I think he'd be a great fit on the Kings, but it's certainly time he moved on from Toronto.
