Agree about the Championship being light years above League One.
Every team, including the likes of lowly Rotherham, appear to have two tall, strong, not-slow, calm, positionally excellent centre-halves, who are completely unflustered by the huffing and puffing of League One quality strikers...
Ditto re CMS, but at a far more devasting cost to a finite player budget - £2.5m and £3.5m in payroll costs. At Championship level "what did Poyet ever see in him?"
