As a Sens fan I'll use them as an ezample to get my point across. The Sens goaltending was pretty bad from 08-11, with Gerber, Leclaire, and Elliott. Then near the end of the 2010-11 season where they were a bottom 3 team, Bryan Murray traded Elliott for Craig Anderson. Craig was a backup until the season prior where he played 71 games for a playoff Avs team, but had a SV% of .897 that season before the trade. In Ottawa he was amazing the rest of that season with a .939 and 11-5-1 to lower the teams' draft position. The next year nobody predicted Ottawa to be good but they were because of an elite 1C and an emerging superstar D-man, but the backbone of the success was a good goalie.
My point being is that you have bad goaltending until you don't. It's not outside the realm of possibility that Wilson buys out Jones, makes a trade or signs a free agent goalie, and if you find the right guy, a weakness can be a strength in a hurry. Maybe use a true tandem approach with [insert name here] and Melnichuk.
