It's disappointing, especially because he was a part of the Pronger trade, but I don't think he was ever considered to be anything more then a minor piece in the Blues rebuild plan. So, in conclusion, meh.
It must be kind of embarassing to potential NHL players when they do clear.
Was it as embarassing to all the potential NHL players who cleared last year? Oh, wait - I forgot, last year I remember reading that [insert player here] was a lock to be claimed on waivers about 200 times ... and hardly any of them were.
Then again, you'd have to understand that (A) to claim a player, you have to keep him on the NHL roster [because to assign him to the minors, you have to waive him yourself], (B) some teams flat don't have the cap space to claim a guy, and (C) for those that do, it means replacing someone on their then-current 23-man roster with the newly acquired player [and maybe risk losing one of those guys to waivers as well].
So no ..... I don't think anyone finds it that embarassing - because being claimed on waivers is very much the exception rather than the rule, and not because 29 other teams think the player sucks eggs.
