Beginning to think you have used parallels in error - when 'similarities' is more grammatically correct and accurate! The differences you say don't erase the argument is a proposal of convenience. The differences prior to Monday alone demolish your argument. You should be aware that during the season
the team have raised their game several times so that should be a factor to consider prior to forming opinions on. As far as I can remember of Boothroyds season(s) there were very few if any of mitigating examples of decent displays. That run in compounded with the loss to York quickly followed by a truly negative display at Wycombe summarised Boothroyds season. This season we have had several decent displays which alone dismantles your paralled theory. Like the way you ignore the Covid-19 pandemic which ironically throws form out of the window as proved by last Monday.
