Jiggy gives the team the best chance to win? He hasn't done that since he fell off of a cliff after his winning streak. We don't know what Berra brings yet. For all we know he'll steal the next game he plays in. You don't think Jiggy will be helpful in the dressing room during the playoffs? He's been through it all.
Jiggy and Berra give us the same chance to win, which is slim to none with their current play. Having Allaire work with Berra for a month isn't going to change some very major flaws in his game. We've seen it, Calgary fans have seen it, he isn't ready yet.
Giguere at least shows he can be a brick wall, even if it was almost 5 months ago. Also, of course Jiggy will be helpful in the dressing room, I don't think anyone has stated otherwise.
