I'm going to imagine Mickey calling him into his office and giving him a detailed history of the FDI in Italy and asking him to delete the tweet.
I imagine Mickey pulling him into his office, slapping him across the face, and saying
"Delete that tweet you ignorant little bastard."
Buschini cries in pain and anger and says
"I'm sorry coach.Why?!?"
Mickey goes onto explain why they're racist quoting Mussolini and Hitler and at one point Mother Theresa. Buschini understands and grows. His blubbering continues as he responds...
I didn't know they were racist."
Then Mickey hugs him and rubs the back of his head (very manly like, no homo) repeating
"I know you didn't. I know you didn't. Just make sure you keep punting like a champ and I'll forgive you."
Or something along those lines. It was very movie like.
