Because they've changed the football style from that which existed at the start of their tenure and he hasn't?
Potter changed a side that played pragmatic, counter attack football, hitting the targetman with long balls, into a pressing team that look to play the ball on the deck.
No, because being hard to beat and being beaten aren't the necessarily the same thing. e.g. RB would lose by the odd goal, SB's team gets beaten comfortably, but they're both recorded as a loss. Compare the GA columns. Look at the football with unbiased eyes.
