You betcha!! That is part of what being a true fan is all about. I'll knock them as much as the other guy when they deserve it, but, always have been and always will be a Leafs fan. Can't stand bandwagon jumpers, or, when people switch "their" teams, just because they are winning.
Will they make the playoffs, still a long shot, but as long as they continue to improve and move in the right direction things are looking up.
