I like Looney. He's young, plays hard, and is a good versatile defender. I wouldn't pay him big money or anything but he'll be well worth his contract if its below 10M/y.
I'd actually prefer Parsons to Whiteside lol. I feel like Whiteside has some Dwight in him as far as the lockerroom goes (Whiteside wasn't mentioned by Kirschner though, while Parsons was. I just put it together based on how he is expiring, makes enough money to fetch two of our bad contracts, and is probably available for trade).
