They are cooked.
The Panthers decided in game three if they couldn't win the Leafs were going to pay holy hell, well the Panthers proceeded to hit, cheap-shot and goon their way through the game. At the time I can remember what is the point of this? Is it just to be a ass? Nope, the point was they are the Champs for a reason and the Leaf were for 7ish periods making the Panthers look human. All of that goonerish behaviour in game three translated to game 4 where the Leafs simply wanted nothing to do with the Panthers. The Leafs quit before the puck was dropped for game four.
The Leafs playoffs is cooked. they will get to play 12 games but in reality their playoffs ended in game three in the 2nd period.
The lead in game 3 was a wasted opportunity. The Leafs are simply out desired by the Panthers, the Panthers want round three, the Leafs want to go home.
Sooooooo....
