Ruutu, Cooke, Avery, Tucker, Barnaby, Gauthier, and most definately Domi (who fights, but pulled a Yertel the Turtle worthy duck and cover on Robyn Regehr the other night) to name a few.
Tucker fights and if Domi is a wimp, I don't know who isn't.
As for the 'turtling' with Regehr, Domi was already down after throwing a big hit when Regehr decided to drop the gloves. Tie loses the height battle when on his feet, was he suppose to throw them on his knees?
Boughner? Really? I've seen nothing from him that would suggest that he's a turtle. He wouldn't fight earlier this season because he was playing with a broken wrist (which he broke on somebody's face, btw) but other than that he's been in everybody's face all season and since his hand/wrist healed he's actually fought a few times.
