Personally, I think (and this is seemingly confirmed by interviews with the players) that Hughes is a good Head Coach - he gets the best out of players, he gets the players on board, the tactics do get results (as this season and his previous seasons at Stoke show), and the players seem happy and fit with his training.
However, my reservations with appointing him is that we would have a triumvirate of Hughes, Reed, and Wilson making the key off-field decisions. All three of them have player recruitment histories that can only be desciribed as average-at-best: Reed (as most people on here seem to agree) doesnt have the greatest player recruitment history, and the same could be said with Wilson. On top of this, especially what has been by the Stoke players and staff, Hughes doesn't have a great recent record of signing players (e.g. Wimmer, Bojan, Jese, Affeley, etc.). Combining these three worries me, especially as we do need some quality additions to help stabilise us and move back up the table.
