Too early to say. He is still improving from many injuries. The next 2 months will tell the tale as far as his future here. If Gillis thinks some of our prospects can step up next year and bring close to (Or more) than Booth at a fraction of the cost, then Booth may get moved at the deadline.
Until then, it makes no sense to move him unless Gillis can trade him for an NHL-ready player with a better skill-set. Not likely that happens.
