If the only guys out there on the street right now are guys like Suisham, who was pretty much cut for to many misses, then I don't think making a change at this stage is worth it. If there was a kicker you'd have 100% confidence floating out there to kick in Lambeau in December, go get him, but let's be honest here, there isn't one.
At this point of the year, don't shake what little confidence Mason might even have left. Continue to express confidence him, hope he can shake himself out of it, and some how pray Mason Wide CRightsby doesn't cost you a big game down the stretch.
You just better hope Thomspon is doing his homework on kickers coming out of the draft next Spring, because I'd be absolutely floored if they do not bring in some legitimate competition for Mason next year.
