Interesting question. I'd be ok moving him, or buyout. I think 4.5 mil is too much for another Higgins type player. 2.5 - 3 mil is more fair for Burrows.
Lack should not have started, he's been good but he is a rookie and young. These penalties are brutal, and some are justified. Dumb, dumb plays by our players. Story of 2014...
