Good work. So many variables, as Cyclops says, but interesting all the same. Worth noting that Trollope didn't make it to twenty. While it's too soon to judge Morison, I see him as similar to Ole and Trollope in that he's trying to move us from one style of play to another (I never quite worked out what Harris was trying to do) so, while it hasn't been all plain sailing, I'd say he's dealing with the transition more successfully than those two did so far.
Off topic but for those who think that Morison couldn't fail to improve both our football and our form after McCarthy left, it's worth noting that McCarthy left Ipswich when they were 12th in the Championship in April 2018 and they finished bottom the following season, 13 points from safety.
McCandless left to manage Swansea the following season.
