It’s baseball season, so here’s hoping you have a scorecard at home.

What you’ll need it for, however, is hoops, not anything to do with the diamond.

Because with all the comings and goings on the Sun Belt Conference basketball front lately, one sure would come in handy.

Along with a pencil.

And an eraser.

Where it all leaves a UL team that made it to the postseason last month — but also finished just .500 — remains to be seen

But what is certain is that with today’s opening of the NCAA Letter of Intent basketball regular signing period, there are both blows to absorb and opportunity to seize for the Ragin’ Cajuns.

The revolving door, in a nutshell "¦

» North Texas freshman star Tony Mitchell: Staying.

» Georgia State: Coming, eventually.

» Western Kentucky freshman star Derrick Gordon: Going:

» Denver: Going.

» NBA legend Isiah Thomas, head coach at FIU: Gone.

» Raymone Andrews, J.J. Thomas, Josh Brown, Darshawn McClellan, Scottie Farrington and David Perez: All out as well.

» Matt Moss and Kasey Shepherd, if they sign as expected with the Cajuns: En route.

Word that Mitchell will remain at NTU broke Monday, when the Sun Belt’s Freshman of the Year and likely late first-round pick revealed he intends forego early entry into the upcoming NBA Draft.

That seems great for the conference, but it can be argued as either good or bad for UL.

On one hand, the Cajuns contained Mitchell and beat the Mean Green in each of their two regular-season meetings.

On the other, it was Mitchell and North Texas that ousted UL from this year’s Sun Belt tournament.

Another of the conference’s talented freshman from 2011-12, meanwhile, is leaving.

Not for the pros, though.

Rather, reports late last week had Gordon — a third-team all-Sun Belt pick — deciding to transfer from WKU so he can play closer to home in New Jersey.

The seventh-seeded Hilltoppers won the Sun Belt tourney and made it to the NCAA Tournament with the highly regarded guard, so the Cajuns shouldn’t be too broke up to see him go.

But Gordon’s departure is just one twist to a decidedly new-look Sun Belt for 2012-13.

Denver — whose Princeton offense-influenced style under coach Joe Scott is greatly respected by UL coach Bob Marlin — is bolting the Sun Belt for the WAC after this school year.

That may mean another break for the Cajuns, who beat the Pioneers in overtime at home in early February but got trounced by them (77-52) in Denver later in the month.

Yet on Monday it was officially announced that Georgia State will join the Sun Belt in time for the 2013-14 season, and the Panthers are no b-ball slouch.

Once coached by ex-Maryland coach Lefty Driesell, GSU went 22-12 this past season under Ron Hunter and made it to CollegeInsider.com Tournament.

That’s the same tourney in which UL played last month, when it lost a first-round game to Rice that left the Cajuns 16-16 in their second season under Marlin.

As Marlin prepares for his third season, one well-known Sun Belt coaching face will not have a fourth.

That Thomas was fired by FIU last Friday, however, should come as no great shock.

The only surprise is that the canning came just five days before signing day, and not closer to the end of his third season in Miami.

Thomas did evidently have the support of his players, who walked out of their postseason banquet Monday night to protest Zeke’s ouster.

And he has an undeniably impressive playing resume: Final Four Most Outstanding Player in 1981, when he led coach Bobby Knight’s Indiana Hoosiers to a national championship; Detroit Pistons point guard from 1981-94; 1990 NBA Finals MVP; two NBA titles; 12-time NBA All-Star; voted as one of the NBA’s 50 Greatest Players in 1996.

Yet things never really have worked out for Thomas as coach, either in the NBA or the Sun Belt.

He had three .500-or-better seasons coaching Indiana from 2000-03, but the Pacers lost in the first round of the playoffs each of those years. And the New York Knicks were fairly terrible when he coached them from 2006-08, missing the postseason both years and going 23-59 in his second season. At FIU, the Panthers were 26-65 in Thomas’ three seasons.

UL was 3-0 against his teams, suggesting whoever replaces Thomas may present the Cajuns with more of a test.

That only means more trial next season for a Marlin club in flux.

Longtime starting point guard Andrews and 2010-11 freshman star Thomas both were suspended late in the season for "conduct detrimental to the team," and neither will return.

Brown, the Cajuns’ leading scorer in 2011-12 and a second-team all-Sun Belt pick who also was named over the weekend to the Louisiana Sports Writers Association’s All-Louisiana second team, won’t be back either.

He’s gone along with the Cajuns’ other seniors, fellow starter McClellan and reserves Perez and Farrington.

So Marlin is re-stocking, with at least one fall signee — Hammond-St. Thomas Aquinas swingman Steven Wronkoski — expected to join spring commits Moss, a big man from Anacoco High who played last season for Charis Prep in North Carolina, and Shepherd, a guard from the Houston area.

After not one but two straight .500 seasons, the Cajuns have hopes for their first winning season under Marlin in 2012-13.

However many more faces change between now and then, though, is anyone’s best guess. So be sure the scorecard is ready, the pencil is handy and the eraser has some rub left.
