For SURE Jones lucked out, he got had, it happens... He didn't give up though and it paid off as Heatley failed to do anything worthwhile with the opportunity. He did a fairly good job getting his skate back to the post, but really could have been beat even along the ice had Heatley handled it well. (Not being overly critical of Jones here, its hard, mistakes happen... hence goals occasionally)
I think we see Jones the whole game. He hasn't switched out a lot and I think they are getting him ready to start the season.
