There’s been a lot of talk in this race about what makes a "real man." A man does what’s right when no one is watching. He upholds his commitments to his family and neighbors. He doesn’t lie, cheat, & steal his way through life. Real men serve others. Weak men serve themselves.

So you know how heartbreaking it was for the Blue Jays to lose in 7 games after not winning a title in 30 years? That was the Dodgers in 2017. Now imagine the Blue Jays and their fans finding out in three years the Dodgers cheated throughout this 2025 World Series like the Astros did in 2017.
