It's pretty funny how when you look over the list of acquisitions and impact it's mostly centered around guys we traded for who stuck around.
Vrbata
Morris
Langkow (pt 1)
Vermette
Heck you could go back to Roenick too. And I'm leaving out a few we traded for at a young age like Z, Ballard, Mara.
You look at FAs, you're down to Smith, Burke, Whitney and Jovo. I'm not sure Whitney played here long enough to qualify for my tastes.
The answer might be Burke. He didn't carry them as far, but he carried a worse team to the playoffs and put up numbers for longer than Smith. Jovo had a similar curve as Smith, starting off well and the last 2-3 years went into the ground.
