Absolutely spot on.
1. Ramsey lingers on the ball and gets caught in possession far too often.
2. He is unaware of what is happening around him, meaning he can't pick a pass.
3. He can't shoot to save his life (but maybe the lives of others

).
4. He doesn't track back enough when he is played as a CM.
5. He doesn't offer any pace when he is played on the wing.
6. He isn't inventive enough with the ball in advanced positions.
7. He is too inventive with it in risky positions, leading to loss of possession, and goals against.
It's far too risky to play him as a CM. Playing him as a winger is a waste of a player. You might as well start with 10 men. His only possible position is as an AM, but I'd rather have Cazorla, Wilshere, Arshavin, Podolski, or even Arteta in that position before him.
