Or take the time, with WVU up just 42-37, when Tinnon and Damier Pitts had an easy rebound of a Truck Bryant missed 3-pointer. Somehow, the play ended with Tinnon watching Pitts fall out of bounds with the ball, giving WVU the ball back.
And then the Herd lost another rebound off a Gary Browne miss. Finally, Jabarie Hinds' mid-range jumper swished, making it 44-37. The Herd never got closer.
"It was all miscommunication. I was running for the ball, Pitts was running for the ball and I was trying to tell him I had the ball and was going to get it," Tinnon said. "It was a misunderstanding.
"That's how the whole game went. We were chasing balls, and we weren't getting them. We weren't focused enough to go get them, and that killed us."
By all rights, the Herd should have been ahead at the half, perhaps substantially. It took a 27-20 lead with 3:12 left, on a spectacular 12-3 run engineered by DeAndre Kane and Justin Coleman.
Kane scored off a steal, scored on an alley-oop pass from Pitts and scored off a Yous Mbao block. But he and his teammates probably got too greedy, misfiring on two lobs.
Had Kane connected with Coleman on an attempted dunk, Herd fans might have jumped out of the building. That missed, and so did Kane's next lob, inside for Robert Goff.
Before those, the Herd allowed WVU to rebound a missed free throw, which eventually resulted in Aaron Brown's bank-shot jumper. That, and an awful turnover on an inbounds pass with 5.6 seconds, allowed the Mountaineers to tie it before the first-half buzzer.
"We did a poor job closing out the first half, and it carried over into the second half," Herrion said.
And when it carried over, Marshall suffered its second 20-minute stretch of malaise in the calendar year. It must forget that by Saturday, when it travels to Southern Miss in its first game as C-USA leader.
Herrion knows he will have to re-instill his values in his team in short order. It starts with the effort plays - offensive rebounds, loose balls and the like.
"They got to every 50-50 basketball," Herrion said. "They dove and we bent. Ball on the floor and we bent, they dove. There's a big difference."
