See, this is WHY we shouldn't have let Schenn go, I really feel under Carlyle's toutalage Schenn would have been a solid partner for Phaneuf.
Schenn doesn't have the mobility to be a top nhl pairing defenseman. His high end potential IMO is a Brooks Orpik type player. Which is ok, but nothing exceptional.
Ian Cole makes too much sense here, he looks like a young Beauchemin, whom I think is your stereotypical Caryle player. I'm watching Coles youtube clips and following in love with his game. He hits hard, he fights, but has more mobility and a better fitness level then Luke Schenn. Cole clearly has that Beauchemin, B.Stuart, Suter type game about him. Has offense, can fight, can move the puck, and more likely to Stuart, he is willing to throw the occasional big hit (actually seems much more keen to them then any of the aforementioned players). Seems to have very similar attributes as Bogosian, but he just doesn't have the sexy draft position (and likely doesn't have the offensive ceiling that people expect\ed from Bogosian).

In all honesty, I think St.Louis is the team to look too, when\if your considering a blockbuster deal. They have pieces we need, and we have pieces they could use. They have a bunch of tenacious\hard hitting top 6 players, but might be lacking in the offensive department. Berglund is a potential top C, but definitely is looking like a guy who won't realize it, UNLESS, he gets a change of scenery.
