Ignorant to say the least. The league is very physically demanding and competitive, with a lot of pace and a sprinkling of top quality players. Just because BWP has finally found some confidence and a team/league that suits him doesn't mean it's a terrible league (although I'll concede it's not brilliant). He'll have to defend vs experienced players like Keane, Dempsey, Martins, Kaka, Giovinco, Gerrard, Maloney, Altidore, Doyle and whoever moves there this summer (Ronaldinho, Hernandez and Drogba strongly rumored) and quite a few speed merchants (David Accam, Erik Hurtado, Lloyd Sam, Dominic Oduro, Kakuta Manneh, Fabian Castillo etc) who are always a handful.
For a player making his FIRST steps into professional football, MLS isn't a bad place to be. Certainly no worse than say League 1 or the Championship, as we can easily keep tabs on the player and we can be sure that he is playing the right style of football. When he comes back to City we can loan him to a better league as he'll have had some public exposure. Not to mention he'll be learning from the excellent Andoni Iraola.
