"We just can't have that many turnovers when they're playing man to man and expect to win the game," Beilein said grimly. "We just can't seem to get over the hump against NCAA tournament teams, and I think with the way Seton Hall is playing that they are putting themselves into position to be an at large team.
"Maybe I'm expecting too much from this team, but that's the way I am. We've shown we can play with teams like this."
WVU started off both halves with dry spells, and gave up a 13-0 run at the end of the first half that turned a four point lead into a nine point deficit at the buzzer.
The Mountaineers continued their recent trend of poor shooting by converting only 40% of their shots from the field. That, compared with the Pirates' 49% shooting mark, gave Seton Hall the advantage they needed to secure the win.
WVU agin hurt their own cause by missing four easy layups. Those shots, combined with a couple of in and out jumpers, may be weighing on the young Mountaineers' psyches.
"We started out the game with an in-and-out, an in-and-out, a back of the rim and a missed layup," Beilein said of early shots that just wouldn't fall. "Sometimes when that happens, it plays on our minds and we worry about missed shots rather than just executing the offense."
After falling behind by double digits in the second half, WVU rallied to cut the Pirate lead to two points late in the game. Seton Hall, however, responded with a 9-0 run that pushed the lead out to 11 points with just over a minute to go.
The Mountaineers then staged a late rally to cut the deficit to three, but it was too little, to late. During the rally, WVU failed to covnert scoring opportunities resulting from two missed Pirate free throw attempts and a Seton Hall turnover.
West Virginia next hits the road for visits to Syracuse on Tuesday and a return visit to the Hall next Saturday.
