I've always been free with team building advice but generally keep coaching advice private. The one thing I will tell you that you may already be doing (but might not) is that you can really, really push your players' minutes if you get that first round bye. If you're not bumping guys' playing time by about 10% (so, playing a 40mpg guy to 44 minutes on the depth chart; 30mpg to 33, etc), then you should.
Another thing is that I tend to not go overboard on coach settings during the regular season, but in the playoffs, I'll pay more attention to the matchup and adjust things more. I know several other owners who do the same, so that is another thing.
Then there's the underlying issue that 7 games is not enough to establish anything close to normalization, and the better team therefore does not always win. The obviously superior team almost always does, but if it's close, well, good luck.
