I just have to reiterate that any website that makes these "Top 10" lists and makes you click to a new page for every single item needs to be take behind the barn and shot.
As for DBG's list, I think it's actually pretty poor.
Johan Franzen is on his list for 3.95M. The guy has 34 points in 40 games and every single year he has been a lock for 20-30 goals and 50+ points. He has some injury problems but I fail to see how a 4M plays is one of the worst contracts in the league...let alone 10th.
Similarly he has Nathan Horton at 11th worst. I understand the injury risk, but his defensive play, his ability to be a leader in the dressing room and be a core component of a Columbus team lacking an identify is pretty significant. Not to mention that he plays really well in the postseason. 5.3 million is pricey and the term is risky, but I think you need to take the cap situation of the team into account too. Columbus isn't going to run into the ceiling and they need to spend to attract players to a team with no playoff success to hang their hat on.
The rest of the list is pretty reasonable. Leino, Clarkson, Weiss, Clowe all have terrible track records so far. Clarkson and Clowe really don't have any semblance of a shot at being worth their contracts. Weiss maybe has a small window to rebound but things look ugly for him and he always struck me as a guy who was hyped based on small sample sizes of good play. If Weiss wasn't Canadian I think he gets treated more like a Havlat kind of guy who is good but gets trashed on for not being great.
