Herrion said Tulane is a challenge to guard because of its ability to drive to the hoop, and Davis is a shining example of that.
"He's been very effective in the conference," Herrion said. "He drives it as a post guy, and he gets his back to the basket and gets to the free throw line. He can drive, he can rebound really well and he gives them a post presence."
Spikes said Davis' style is becoming more popular among college basketball's post players, but wasn't something Marshall's had to deal with too much during conference play this season.
"He can start from the perimeter and work his way down into the post," Spikes said. "You don't run into too many post players in Conference USA doing it."
Davis isn't Tulane's only scoring threat. Sophomore guard Ricky Tarrant is seventh in the league in scoring, averaging 16.1 points per game. Marshall retaliates with a balanced scoring attack.
The Herd has four players averaging double figures, including two in the conference's top 10 - sixth-ranked Elijah Pittman (16.3 points per game) and 10th-ranked DeAndre Kane (14.9 points per game).
Yet Marshall will need a little more scoring balance than it saw Saturday in an 86-79 loss to East Carolina. Robert Goff scored a career-high 27 points, while Pittman scored 21 and Kane scored 20. But only three other Herd players scored a point and none of them scored more than Dennis Tinnon's six.
Marshall's struggles have put the team in a predicament where it's win or go home until next season. Still, the Herd was playing for C-USA's tournament title and its automatic NCAA tournament berth just last season. Spikes said that experience, and an unwillingness for their season to end, will drive the players this week.
"If you don't want to go home early, you've really got to step it up," Spikes said. "If you're a senior, that one loss is really scary. As seniors and with the guys who were here last year, that's where our desperation's going to come.
"We know what it's like to get there," he added. "We have to stick together and do it."
