This season,
WF has won games with the following standing at halftime:
led Columbia by 1
led UNCA by 5
led Davidson by 3
led CoC by 2
led Cal State by 7
led Xavier by 9 (outscored by 7 in second)
led NC A&T by 7
trailed Pitt by 3
led BC by 7
led Clemson by 3
WF has lost games with the following standing at halftime:
trailed BC by 15
tied with Charlotte (also tied at end of reg. - lost in OT)
trailed Arizona by 6
trailed Penn State by 18
trailed NC State by 9
trailed FSU by 7
trailed Duke by 26
trailed VT by 2
led Clemson by 6 (lost by 3)
led UVA by 7 (tied at end of reg - lost in OT)
led ND by 5 (lost by 10)
led UL by 12 (lost by 10)
So losing leads after halftime is actually a recent development, with each of the last 4 games involving that (and being the only games this season that it has occurred - although Xavier did make a run earlier this season). On a related note, WF is not great at overcoming a halftime deficit, having won only one game this season where they entered the second half losing. Conference games are bolded.
I particularly liked this analysis, so I decided to expand on it. I took a look at all ACC games under Danny Manning in which the Deacs held a halftime lead:
We had the lead at the half in 16 wins and also in 25 losses.
The 25 losses includes losing games in which we had a halftime lead of 12, 10, 8, and 7 (4 times).
The worst losses for the Deacs would be last night (swing of 22 points), vs clemson in 2015-2016 (swing of 22 points), @ UVA in 2016-17 (swing of 18 points), @FSU in 2016-17 (swing of 17 points), and @ ND this year (swing of 15 points).
