The final day of the regular season has arrived, with one playoff spot to decide, seven of the eight first-round matchups still unknown and nine different seeds still not clinched.It also is the last day that Dallas' Dirk Nowitzki and Miami's Dwyane Wade will be NBA players before retirement. Dallas is in San Antonio, Miami is at Brooklyn. Nowitzki and Wade played their final home games on Tuesday night, both scoring 30 points apiece.It is the first day of the offseason for a few teams, including the Los Angeles Lakers — whose season ended Tuesday with a loss to Portland and team president Magic Johnson stepping down in a move that few could have predicted. Washington, Cleveland, New Orleans and Phoenix also are done.The only known first-round matchup is in the Eastern Conference, where Indiana and Boston meet in Round 1. Every other matchup remains to be determined.There are no major individual races left to decide: Houston's James Harden is the scoring champion, Detroit's Andre Drummond the rebounding champion and Oklahoma City's Russell Westbrook the assist champion.But as for the playoff picture, it comes down to the last day in both conferences.EASTERN CONFERENCESeeds entering Wednesday1.
