The cap room won't necessarily be for free agents though anyway. That extra cap room will give him a lot more flexibility in trades because he could absorb a bigger contract without having to match salaries. And with Detroit not being a very attractive place for free agents that might be the route he's taking.
I have no idea what trades could possibly be out there that would make sense. Just pointing out that cap space isn't just for a free agent bonanza.
Good point.
