It’s such a crapshoot. Between needing to have a great team, needing that great team to stay relatively healthy, and needed that great team that’s stayed relatively healthy to win a good 4 to 6 games (1 or 2 of which are playoff games) that come down to strokes of pure luck you have limited control over…winning a SB is EXTREMELY difficult.
Teams like the Patriots, and the Chiefs as of late, have given many a false impression of how easy or hard the task is.
