The one nice thing about this Pacer's match up is at least its a healthy team. When you beat the decimated Heat or the Mitchell-less Cavs its hard to know how to feel about that becasue it sort of ruins the calibration.
But we know what the Pacers are. They have one All-NBA level guy in Haliburton and one solid All-Star level guy in Siakam. They fill out their starting lineup with solid shooting role players who make sense together. After acquiring Siakam (after the all star break) they went 16-10 or about a 50 win pace and had the league's second best offense and an average defense. They have a pretty deep bench, and they like to play very fast.
They are a solid team. So seeing how Boston plays against them will be a good calibrator.
