NFL at the MCG?

A bunch of credible American media outlets are reporting that the NFL will send the Philadelphia Eagles and Los Angeles Rams over to Australia for an October 2026 regular season game at the MCG.

A few tongue-in-cheek questions from this American:
1: Eagles at the MCG: How many Collingwood fans just became Rams fans too?
2: Which American NFL team most closely matches it's AFL "counterpart"? The four options are Philly/West Coast, New Orleans/St. Kilda, New York Giants/GWS, and Detroit/Brisbane.
3: Which AFL fanbase will send the most fans to watch? North with the Sav Rocca link from years past? Collingwood to boo the Eagles?
