Player and tactical matchups to watch

Bulls at Hawks, monitor wing spacing and how the Hawks use pick and roll. If two-way wings get early minutes, expect fourth quarter usage shifts. My locker-room tip, watch rotations in the second period for endurance matchup clues.

Raptors at Nets, look for mismatches on the perimeter. A Nets interior defender may draw foul trouble early, opening line ups for drives.

Heat at Knicks, both teams play physical defense. Expect halfcourt sets and contested shots. This boosts value on points under lines.

Spurs at Wizards, this is a development game. Young guards take high usage. Track rookie minutes for prop edges.

Bucks at Timberwolves, star matchups decide tempo. If a primary scorer rests or exits, the game script flips to bench-heavy minutes.

Rockets at Kings, late pace battle with offense favored. Totals often move up late in such matchups.

Key insight, watch early rotations and foul patterns to anticipate second half scripts.
