The 2023 XFL postseason begins Saturday as the Houston Roughnecks (7-3) host the Arlington Renegades (4-6) at TDECU Stadium in the South Division Championship at 7 p.m. ET. Houston won both regular-season meetings with Arlington, posting a 23-14 home victory in Week 2 before cruising to a 25-9 road triumph in last week's finale.

The North Division Championship takes place at Audi Field on Sunday at 3 p.m. ET, when the Seattle Sea Dragons (7-3) visit the D.C. Defenders (9-1). Seattle gave D.C. a tough time in the regular season, but D.C. managed to sweep the series with 22-18 and 34-33 victories.

Houston is a 6.5-point favorite in the latest Roughnecks vs. Renegades odds from Caesars Sportsbook, while the over/under for total points scored is 41. Meanwhile, D.C. is a 3-point favorite in the latest Defenders vs. Sea Dragons odds and the over/under is 48.5.

Before you make any Renegades vs. Roughnecks and Sea Dragons vs. Defenders picks or XFL postseason predictions, you need to hear what pro football expert R.J. White has to say.

White, a Fantasy and gambling editor for CBS Sports, consistently crushes against-the-spread picks and went 535-450-30 on his ATS picks from 2017-22, which returned more than $3,500 to $100 players. He also closed the 2022 NFL season on an incredible 107-80-6 run on his last 193 against-the-spread and total NFL picks, returning more than $1,800 for $100 bettors.

White has crushed not only the NFL but also the XFL during its abbreviated 2020 season, going 16-4 on XFL ATS picks before the league suspended operations. He closed out the 2023 regular season by correctly picking all four games last week. Anyone who has followed him is WAY UP.

Now, White has locked in his picks for the XFL playoffs. We can tell you that he's leaning Over on the point total for Defenders vs. Sea Dragons. "Both teams have great offenses, but the Defenders are begging for a name change, giving up 30 points per game in the second half of the season to opposing offenses," White told SportsLine.

White also has two plays in XFL semifinals, including one on a team whose offense "performed much better in Weeks 7-9 than it did the first six weeks of the season." You ABSOLUTELY need to see his picks before making any of your own.
