The lack of a commerical and marketing presences even tho Milan, Juve and Inter are 3 of the biggest clubs in world football, they lack behind the other big teams in europe in that aspect.
Transfer system, where co ownerships and payin for half the rights is the only way young players can get games instead of the normal loan system elsewhere. + Contracts for snr players blockin the path of younger players. Mention Udineses scouting network. SPLa Liga minus the big 2 didnt have a great transfer window spending wise and Spain is more or less in the same situation as Italy is. Any transfer over 8 figures is a big transfer, regardless of how high the figure goes. Like I said Italian teams do more co ownership deals so they rather spend €15m on half the rights of 3-4 players then invest it in 1 player.
The change over from the lire to euro and the effect it had in a 10 year period.
PED test, i think Italy/Serie A have more high profile failed drug tests than any other top leagues.
Too many old fukks run clubs and dont have a vision. Projects wirh new managers last all of 3 games.
Serie A struggled to shake off its Catenaccio tag. Which in turn means its hard to bring outside investment as the produce is seen as boring.
Other than that, you touched on most of, if not all of it.
Dont know if you've come across this in your research

but at the same time it works well with showing how teams can kick around money while Serie A is doing none of it
