Wait, since when was it difficult to find a cheap back-up? Finding a guy for a shade above the minimium has never been difficult...in fact the Pens have had a conga-line of them throughout Fleury's career outside of Vokoun. Sabourin, Conklin, Condon, Garon, Greiss, Johnson, Zatkoff...all had minimal cap hits and came from outside the organization. Plus there's Jarry in WBS as a safety net.
With the salary coming off the books this year this isn't even remotely a concern, even if the Pens wind up being stuck buying Fleury out...plus let's not act like back-up on a legitimate contender doesn't hold some appeal, many of those names I listed went to Pittsburgh on a discount because of that chance.
