St. Louis ? There’s no such thing as a winning streak at Saint Louis. Or a losing streak either, for that matter.

The stat sheet says that Billikens’ big second half against Fordham on Saturday means they’re due for a fall. Why? Because they’re the epitome of a .500 outfit, having alternated wins and losses throughout the first 19 games of the season and the last 21 games dating to the end of last season.

At times, they’ve won against the odds. At times, they’ve stunk up the joint. Most of the time, they’ve seemingly done whatever it has taken to keep this oddity alive.

“It doesn’t have a life of its own,” coach Brad Soderberg said after the Billikens’ 42-point second half produced a 64-54 victory over Fordham. “You guys can write about it. But it’s been weird.”

It’s the longest streak of its kind in NCAA sports, and longer than any in major league baseball or the NFL, although the school is unsure about the NBA. The 1974 Philadelphia Phillies and 1981 Los Angeles Dodgers each alternated wins and losses for 16 games, and the 1994 Indianapolis Colts did it for 12 games.

Saint Louis, then, stands alone in its consistent inconsistency. The school is 10-9 overall, 4-3 in the Atlantic-10 and without one shred of momentum, positive or negative, heading into Wednesday’s game at Rhode Island.

“It’s the craziest thing I’ve ever been around,” coach Brad Soderberg said. “I’ve never been on a team, coach or player, where this has happened. I just hope we can take the positives to Rhode Island and see if we can play good basketball again.”

The structure of the schedule has a lot to do with the ups and downs, with a six-game stretch of North Carolina (L), Oakland (W), Mississippi (L), Kennesaw State (W), Gonzaga (L) and Chicago State (W) alternating weak and strong opponents.

But that’s just part of the story, because the streak could easily have ended on several occasions.

l Danny Brown, with a good look at a three-pointer for the win at George Washington on a career-high 23-point night, fumbled the ball and Saint Louis lost in overtime.

l The Billikens scored five points in the final 35 seconds to avoid the upset against St. Bonaventure.

l Kevin Lisch’s long three-point attempt at the buzzer is just a bit long in a three-point loss against Gonzaga.

“Every game you go out there expecting to win, obviously, and when you win one, lose one, win one, lose one for I don’t know how many times that is, that’s pretty amazing,” Lisch said. “Hopefully, we’re going to do something about that.”

Lately, they’ve played just well enough, or poorly enough, to follow the pattern. The Billikens stumbled at Richmond, one of the Atlantic-10 weaklings, then four days later played at its best in a 5-point victory at Xavier, which had been poised to move into the Top 25.

Three days after that, they shot 28 percent and scored only 39 points in a 15-point loss at home to Saint Joseph’s that a frustrated Soderberg labeled as “distasteful.” They played one more awful half against Fordham before awakening. Again.
