We’re one week away from the start of the Sun Belt Conference basketball tournament, and there are still numerous scenarios for who will claim the all-important Top 2 (and Top 4) seeds.

James Madison has moved into sole possession of first place in the league after going 2-0 last week, while Arkansas State, South Alabama and Troy all went 1-1. But the Dukes haven’t locked up anything yet, given how the various tiebreakers might play out.

Appalachian State and Marshall — who are two games back of the lead — also remain in strong contention for a Top 4 seed. The Sun Belt’s unusual tournament set-up and its likely status as a one-bid league for the NCAA tournament means finishing in the top four in the standings goes a long way toward a less-difficult postseason road.

Here are how things stand among the six Sun Belt men’s basketball contenders as we head into the final week of the regular season (games are Tuesday/Wednesday and Friday this week to give everyone an extra day to travel to Pensacola, Fla., for the tournament):

James Madison (12-4)

Remaining games: at Louisiana-Monroe (2/25), at Texas State (2/28)

Has tiebreaker on: Troy (1-0), Arkansas State (1-0)

Loses tiebreaker to: Appalachian State (0-2), South Alabama (0-1)

Split with: Marshall (1-1)

The Dukes — defending Sun Belt tournament champions — are in great shape to finish in the top 2 if they win at least once this week. Going 2-0 would give JMU the outright regular-season championship. That would mean a bye all the way to the semifinals of the conference tournament, which take place on Sunday, March 9.

South Alabama (11-5)

Remaining road games: at Southern Miss (2/26), home vs. Louisiana (2/28)

Has tiebreaker on: Arkansas State (2-0), James Madison (1-0), Marshall (1-0)

Loses tiebreaker to: None

Split with: Troy (1-1)

Note: The Jaguars’ overtime loss to Texas State on Saturday was a painful one, mainly because it limits their ability to win the Sun Belt regular-season championship for the first time since 2008. However, sweep the Golden Eagles and Ragin’ Cajuns this week and they are a virtual lock to be a Top 2 seed because they hold head-to-head tiebreakers on everyone but Troy and App State, and would win the other tiebreakers over the Trojans and Mountaineers.

Arkansas State (11-5)

Remaining games: at Louisiana (2/26), at Louisiana-Monroe (2/28)

Has tiebreaker on: Appalachian State (1-0)

Loses tiebreaker to: South Alabama (0-2), Marshall (0-1), James Madison (0-1)

Split with: Troy (1-1)

Note: The preseason Sun Belt favorite Red Wolves need utter chaos to finish in the Top 2, likely a two-way with App State for either the No. 1 or No. 2 spot. They lose tiebreakers to everyone else, so they might not get into the Top 4 even if they win out.

Troy (11-5)

Remaining games: at Texas State (2/25), at Southern Miss (2/28)

Has tiebreaker on: Marshall (1-0), Appalachian State (1-0)

Loses tiebreaker to: James Madison (0-1)

Split with: Arkansas State (1-1), South Alabama (1-1)

Note: The Trojans’ only head-to-head tiebreakers are with teams behind them in the standings, which would make finishing in the Top 2 pretty difficult to pull off. However, win out and they’re a good bet for the Top 4 thanks to having at least one win over South Alabama (which none of the others still in contention have).

Appalachian State (10-6)

Remaining games: at Georgia Southern (2/25), at Marshall (2/28)

Has tiebreaker on: James Madison (2-0)

Loses tiebreaker to: Arkansas State (0-1), Troy (0-1), Marshall (0-1)

Split with: None

Note: The loss to Marshall on Saturday gave the Mountaineers a near-impossibly rugged road to the Top 2, and they’ll need some help to finish in the Top 4. If somehow App State ends up tied with JMU, that head-to-head sweep could loom large in the bracket.

Marshall (10-6)

Remaining home games: at Old Dominion (2/25), home vs. Appalachian State (2/28)

Has tiebreaker on: Arkansas State (1-0), Appalachian State (1-0)

Loses tiebreaker to: Troy (0-1), South Alabama (0-1)

Split with: James Madison (1-1)

Note: Like App State, the Thundering Herd aren’t likely to finish in the Top 2, but have some handy tiebreakers for the Top 4 assuming they sweep both games this week. If JMU wins the regular-season championship, that head-to-head win could break ties with everyone but South Alabama for a Top 4 spot.
