The schedules overlap in useful ways. Both teams played Virginia Tech and Boston College this month. Pitt went to Blacksburg and won 35-33, while Georgia Tech lost there 24-34. Both lost to BC, but Pitt kept it to one score on the road and Georgia Tech gave up 49 at home. That isn't the whole story, but it's the cleanest comparison these two have.
Mercer44-11
Bucknell59-0For Georgia Tech, the problem is stopping the run. Boston College's Mason McKenzie and Bo MacCormack ran for around 400 yards against the Yellow Jackets, and the 49 points were the most Bill O'Brien's Eagles have scored against a Power 4 opponent. Tech has allowed 34, 34 and 49 in 3 of its last 4 games. The offense has been fine: it has scored 24 or more in every game of its last-5 window. The defense hasn't been able to keep it in games.
For Pitt, the issue is everything since October started. A team that beat Bucknell 59-0 and won the shootout in Blacksburg has scored 17, 21 and 23 in 3 straight losses. The Miami loss is the easiest of those to explain, since that is the best team in the country. The UNC and BC losses were both one-score games the Panthers could have won. At 5-3, Pitt is 1 win from bowl eligibility, and it gets a home game against a Georgia Tech team that just gave up 400 yards on the ground.
The weather shouldn't be a factor. The forecast for Pittsburgh is 55 degrees and cloudy, with 8 mph wind and almost no chance of rain. Two things to watch: whether Heintschel is cleared, and whether Georgia Tech's defense can stop the run at all after BC's 400 yards.
