I wouldn't say Kronwall is dead weight, he just needs to be counted on less at this point. He still has a lot to offer in a lesser role.
As for Howard and Ericsson, I agree. Sadly we're stuck with Howard unless we get lucky.
Kronner is being paid 5 million a year for a job that a number of our GR guys could do (Sproul, Jensen, Oulette). Kronner has a bumb knee and really had a bad season last year. He is not worth the 5 mill and is seriously on the decline.
