If it's true that the players vote to not play in a bowl game, I would respect their decision.
In my humble opinion, there's more reasons to not play in a bowl then there are too play in one...
Clausen and Tate's stock have never been higher and I don't know if either of those 2 would want to risk injury...Notre Dame could run the risk of being embarassed by an inferior opponent...Notre Dame shouldn't be playing in gimmicky bowls; they should be playing in premiere bowl games...For as much as they might need or want the extra practice/playing time, have they really "earned" the right to play in a post-season game? And lastly, they might not want to play as this years team without CW as their coach (the whole "we started the season with him as our leader and we want to end it with him as our leader" type of thinking)...all-in-all it'd be too much risk and not enough reward coupled with the strong expectations and loyalty to what, and who, ND is and all about...Those would be my reasons why they would elect to not play and I'm guessing those would probably be theirs too.
As for reasons to play another game? I can't really think of many solid reasons other than: Because they love the game of football...Because ND fans want to see them play in a bowl game...Because they need the extra practice/playing time...Although all good reasons, and maybe for other schools those would all be good enough reasons to play in one more game, but this is Notre Dame...Expectations and standards are different here; and different in a good way...These players "get" what, and who, Notre Dame is...I would hate seeing ND in the GMAC bowl because I know that that isn't where ND belongs...and if that's the type of bowl they're being offered to play in, then I would hope they would turn it down because of all the reasons I mentioned above...
Again, just my opinion...but I think there are just too many varying reasons as to why they should not play in a low-end bowl game.
