I really like Canady and McMahon. I agree that it doesn't seem right to put them on the fourth line. On the other hand, if those two guys are on the fourth line, it's because some other players are doing very well, which gives the Sioux one heck of a fourth line.
Massen played most of last season with a bum knee. Despite that, I saw him do some things that demonstrated his potential. Maybe it's not saying much, but he was simply awesome against Michigan Tech. I also remember his breakaway goal that Blais said very few forwards in the WCHA could have scored. A healthy Massen teamed with a playmaker like Parise and corner man like Lundbohm might make a good combo.
