Lou got Rielly and that punk Kadri signed to good terms when they were RFA's. If I am a betting man he will do the same with Mathew.
Neither of those players broke out before they were signed. A good example of Lou's work in Toronto would be the Dion Phaneuf contract which he got rid of without any retention.
A bad example would be giving a rookie D with one year of experience, a 7 year deal and the Marleau contract.
Rielly and Kadri look great in hindsight but they were given exactly what they were worth at the time.
