Not convinced on this tbh.
Big players typically don't make runs beyond the last man so you can't play through balls, and rarely do they come as deep as the smaller more technical players to start attacking moves, so you either play it in to feet for them to spin and (try to) make something happen/shoot (like Balotelli) or lump it up for them to lay it off to someone making a run beyond them (Carroll). The best 'big man' forward I can think of is Dzeko because he can just about do anything and has so many more strings to his bow than being a focal point or target for the team, which is why City aren't reduced to lumping it up.
Balotelli is very static as a forward, so there's not a great deal of options open to us. Also, as a result of playing Allen, Henderson AND Gerrard in the team, there's a huge gap inbetween the midfield and Balotelli (when we play 4-3-3) so there's no possible way to play the ball to feet and work our way forward. You hit it across the gap instead, usually to 'super' Mario. Last season, we had Suarez or Sturridge dropping into that hole and Coutinho playing in the midfield hole too.
It's just not a balanced team right now which I think exaggerates the problem.
