That's true for M&D. The other teams don't beat YJ.
Hero's beat YJ at Lax4Cure and G8 2 years ago. Sky Walkers also seems to do well against YJ. They are all very close. It's just too bad that the top 6 or 7 cannot play each other all the time. Driving up the Turnpike for some of those games is really not worth it.
