They still have time but now they need to move one of the four. Also, I'm not sure Jack Campbell, at 29, has finally put it all together and is going to continue playing the way he did this year for years to come. He's had two good seasons in his career but he's never played more than 31 games.
My game plan would be to find a way to solidify the bottom of the roster with capable players, and to stop having the revolving door of aging veterans who won't last beyond a year. Stop the Spezza's, Thornton's, Simmonds', Foligno's, Marleau's, etc. They need a bottom pairing they can actually play too. I think their play style sucks, they need more physicality, but more importantly an attention to defense.
They need guys who are signed for more than a season so they can actually develop an identity beyond the top players.
