Miller really showing his age out there. After being abused by Harris in the 1st, mo had him guarding the SG in the 2nd. This led to Ivey getting PT, which basically gave the team no "shot" on offense (quite literally.)
Miller can be effective against some teams, but against quicker pg's its guaranteed open shots for the opposition as he can't prevent dribble penetration. The Sixers defense collapses, leading to open shots around the perimeter.
Miller was so slow, they didn't even have to run a pick and roll against him.
