I seriously think it's time to move on from Sprong if by December he hasn't figured it out. He's spent whatever good will the coaching staff had on him with the games so far and yeah that's not a lot of games, but the things he's done, it'd almost take a miracle set of games for Sprong to get back into the good graces and I don't know if I see that happening.
His choices for where to be on the ice is just not up to par and jokes aside with his minutes and benchings (he's earned them, I joke about it, but he's earned what Sully has done to him with cutting minutes and benching him), he's a kid that will likely flourish in the NHL when he's moved and has that kick in the rear that he needs from that experience of not being wanted anymore.
He makes bad choices with battling for the puck and losing his man in his own zone far too often. It's not even like the kid doesn't try, he tries, he actually does try and you see it, but it's like he's just not taught to do it correctly or if he was taught, it's not sinking in. The 4th line stuff, I get it, the guy needs to be better 1 on 1 with his defending and knowing who to cover when he's in his own zone.
Honestly, if JR doesn't move him, he's going to have to take the hit he did with moving Pouliot for scraps later on in the season. At this point, Sullivan should bench him and play Grant to see if that sparks him. It would be a multiple game benching though imo, he has to review game tape and sit and practice, the talent is there, but holy crap, the kid is just not putting it together and while he could use some AHL time, we can't without losing him.
