Ultimately it's been 4 games and MIA is up 3-1
If MIA wins game 5, then sure that's not as great a flex as saying you swept them but that's still a flex, and shameful if you're the Celtics
But if Boston wins game 5 and say it's a blowout, then yea mentally they'll be thinking it's the 3-2 Philly series all over again and MIA will be feeling the pressure for game 6.
