This late season swoon is different than the others. Each season should be taken on its own, but past late season losses were far more predictable because of injuries and the opponents were more talented and deeper than WF. In 2019, when Surratt went down against VT (and WF was playing at Clemson next), it was pretty obvious that WF was going to struggle at the end of the season (WF had other injuries as well).
This year, WF is generally healthy, is deeper and was FAVORED in each of the last 3 losses. This 3 game stretch is really the first time when talent differential based on available players did not easily explain the losses. If WF played UNC, NC State or L'ville tomorrow, would expect WF to win those games. In 2019, WF was never ever going to win at Clemson, and was unlikely to win at VT. The 2020 UNC team that made the big comeback against WF was similarly loaded with future NFL players (and again UNC was favored that day). Last year, WF lost at UNC and at Clemson as underdogs at the end of the season. While the results are similar, the scenarios are totally different.
