As I was saying in the Laine thread - there were risk factors, so the return would have be low.. and we got paid to take him, so I'm excited to see how this experiment goes.
By getting paid to take him, it minimizes the downside of the deal, and clearing Harris creates less burden on the log jam on left defense. So add scoring, add an additional high pick in a future draft, and alleviate a defensive log jam.
Upside is he finds his game and we either extend him in line with our salary structure, or retain half and trade him for a huge return at the deadline in 2 years OR use him as an 'own rental'.
Downside is he doesn't and we let him walk or re-negotiate a much more reasonable deal ahead of UFA.
Kent Hughes is a GM. He is making this whole thing look EASY.
