From ESPN’s Pierre LeBrun:
The Red Wings are believed to be among teams interested in defenseman Christian Ehrhoff, whom the Sabres are shopping. He’s got seven more years on his deal after this season, at a $4 million cap hit. What’s better, though, is that $22 million of that 10-year, $40 million deal will have been paid off by the end of this season because it was front-loaded.
I don’t think the Wings would overpay to get him but he would fill a need for a top-four, offensively minded defenseman.
if he's effective for those 7 years, that cap hit is great for what he would bring imo.
