Why cant you replace your "starter"? He has been sub par anyway. If the Canes had been of that mind set in '06, they might have never won the cup.
"Oh, you cant take out Gerber and put in a 21 year old with very little experience!"
You didn't read closely. I didn't say you couldn't replace your starter. I said you couldn't replace your starter and have your other two options reek of inexperience.
Ward replaced Gerber out of necessity more than anything. Gerber had a stomach virus (IIRC) that caused him to lose a lot of weight and generally feel terrible.
And even after the playoffs Ward had, the team was willing to keep Gerber around as a backup. Because they realized it was quite possible Ward was simply "on" during that run and might not be able to handle the 60-70 games of an NHL starter, especially in his second year in the league. And they were right. He struggled a lot the first couple years in the league.
Gerber, again IIRC, declined their offer, hoping to find a starter job elsewhere (which he found in OTT). After that, the Canes grabbed a veteran goaltender to backup for the same reasons stated above.
If they're going to replace Ward as the starter, which appears to be the transition that's taking place, it's still prudent to have an established starter rather than a question mark as a backup in case one of Peters/Anton (whichever they keep) struggles next year.
That established starter doesn't have to be Ward, but if he's been relegated to a 6.3 million dollar backup with an NTC, he's going to difficult to move (to say the least).
