Does winning one more qualify as continuing the dynasty? I certainly don't see it this year but we still have BB so it is possible but I would view it as a 1 off. BB could coach for 10 more years and the best he'll do is win 1. Basically like most everyone else.
S/O to @FrodoBagginz, since you give me an excuse to geek out for a few:
I think these phases are better defined as Ages than Dynasties. The post TB era is like the Fourth Age. We're still in Middle Earth, but it kinda sucks because the Eldar said "Namárië, suckers!" and they ain't coming back!
