The goalie market is over-saturated, but not with goalies like Bishop. He's much younger and will cost a lot less money than any of the other goalies that are available.
He fits the needs of a team that is going to be rebuilding. Tampa Bay seems like a logical choice, but we are in their division next year so that complicates things. Calgary is another choice, especially if they trade Kipp. Winnipeg might be another place as well. They overwork Pavlec, Bishop could be a great 1b.
I also think you guys are undervaluing him. We traded a 2nd for him. He's increased his worth since then. Everyone though that was a fair deal at the time. It only makes sense that he is worth more now. Like someone else said we might be able to get a high 1st rounder for him + a young player. That being said, I don't know why we really need another high first rounder. We actually don't need very much at this point.
I'd love Ottawa to carry 3 goalies next year. Give Anderson 42 games w/ Bish and Lehner splitting the rest. Keep everyone happy and healthy. I remember a thread where it showed that goalies perform much much better in the playoffs when they haven't been worked to death during the regular season.
