Ward - I'm all for it, as long as the term doesn't handcuff Burke if it doesn't work out (see Luongo, Pavelec). I'd do 3 years, and re-sign or not depending on his performance.
Hiller - he's 32. He'll be retiring, or close to it, by the time the rebuild is over. Not worth it to sign an aging goalie, proven or otherwise.
Ramo - not a starter. Period.
Ortio - inconsistent, great one game/period/shift, and awful the next. If he's the Flames' starter going forward, they're in big trouble.
Gillies - completely untested. No way to know.
