I don't expect it to happen, but selfishly I'd be fine with ESPN+ getting the rights back just because I already have ESPN+ (in part) to watch the Bundesliga and La Liga...I probably would've bitten the bullet and gone for Paramount+ this next season if they re-upped with Serie A, but they dropped the Brazilian rights and having Italy and Brazil on the same package was why it would've been worth it to me. (Argentine rights too but I'm not really fussed about Argentine football.) I just can't interest myself in Paramount+, which has basically nothing in their inventory that I care about otherwise, for the purposes of one league only, especially because I've generally not heard good things about their product interface either. I'll live with my boat and Jolly Roger out on the water.
(But fair play to them for putting forth an honest effort in their coverage of the league. I'll give them that much. From that perspective, Paramount+ losing Serie A would likely be a net loss for most viewers.)
