Many things don't appear in game stats. Most of all, you can't see the importance of inside shooting on the cowboys' outside players (Canipel and Jashari).
Yet I see 2 things that are critical, assuming your SF defended on his SF, Duym vs Marshall is a huge mismatch in Joe's favour, and his attack management is much better than yours, leading his attacks to be in general more successful.
TBH, not sure you would have won with a normal ... although playing with inferior enthusiasm didn't help of course.
Last season's B3 campaign ended so for Joe :
