Two more second-round series in the NBA playoffs 2026 get underway on Tuesday with Pistons vs. Cavs at 7 p.m. ET and Lakers vs. Thunder at 8:30 p.m. ET. NBA picks and NBA parlays could target the alternate lines, though they'll likely vary greatly between the two series. The last three Cavs vs. Pistons games have been decided by single-digits, while the last four Thunder vs. Lakers games have an average margin of victory for OKC of 29.3 points. The latest NBA odds have OKC favored by 15.5 points, while Detroit is a 3.5-point favorite in the early game.

From plus-money NBA props like margin of victory to first basket scorers to making NBA predictions on who will be a game's high scorer, your parlay could go in a number of different directions.
