The main differences I see are reduced minutes for starters (though that may be just because of the emphatic wins), timeouts called more quickly when we go on a slide, and increased effort on defense from two players. Also, shots are falling with more regularity, but that's probably just down to increased optimism at the end of a negative/stressful time.
The system looks pretty much the same to me so far.
The three game run is nice, but I'll be reserving judgment until I see how the team reacts to losing a few games. That, for me, will be a more important indication of whether this team has really turned the corner.
