I've been having a look at this league on this cold afternoon and I thought I'd drop a few words for you vios:
I use to look at the box score and analyse it. When I see your loss to WT, there is one thing that stands out. WT's players are ALL making somewhere close to 50% of their shots. I don't know the exact skillset of each of his player but looking at their salaries there is no way his guards can have such a high accuracy.
2-3 zone is fun but when his big men take 34 shots out of 82 with 50%, this is not working. You'll not win games when your defence allows 115pts. Go man to man, let his bigs drop 40-50pts on you but shut down his wingmen.
If you can afford this team all season long, my money is on you to promote!
