When announced. Very few players have come back after two years out and played well so that was a big gamble. They tied themselves to a frankly ridiculously idiotic contract that leaves no room to wiggle and Watsons last playing year didn't bring in a lot of wins. Stat's are great and all but its a team game and, well he couldn't lead his team to a win.
Oh, and they legitimized a rapist so yeah, definitely when it was announced.
Josh has turned into Ryan Fitzpatrick 2.0 without the charisma. A gunslinger who takes chances and can pull off some amazing throws but who also fucks the game with turnovers occasionally.
