I would be very concerned if I were Turkey.... if they lose they need to beat Spain to get to second round, otherwise it is over for them.
They're down 4 at half, the game isnt over. However the coach really needs to have a good talk with them. Poland commited a series of consecutive turnovers there in the 2nd. If the game comes down to crunch-time, we might see more of that. Well, I hope so anyways
The coach's style is obviously very hands off, Don Nelson style coaching. I don't expect him to have much effect.
