Mercer, meanwhile, has looked like anything but an overmatched visitor so far. The No. 17 FCS team routed Presbyterian 62-3, then survived a nervier finish against East Texas A&M, holding on for a 23-15 win despite building a 23-0 halftime cushion. First-year coach Joel Taylor is 2-0, and the size of this week's spread says more about scholarship counts than it does about how either team has actually played this month.
That's the split at the heart of this one. Georgia Tech hasn't lost to an FCS opponent under Brent Key, a streak that reflects the real talent gap here. But Tech's defense has been soft against the run through two games, and a Mercer offense that just hung 62 points on somebody won't be shy about testing it.
Atlanta's forecast for Saturday is muggy and unsettled — 90 degrees with a real shot of rain — the kind of day that usually rewards whichever team can lean on its legs. That's a wrinkle worth watching if Mendoza's ankle limits how much Georgia Tech can ask of him from the pocket, putting extra weight on a Yellow Jackets run game that hasn't answered many questions yet.
There's no live betting card on this one yet, so take this as a scouting report rather than a wager. What two weeks of tape make clear is that Georgia Tech is still the better roster by a wide margin, but 0-2 teams don't get to treat any game as a formality, and Mercer hasn't given anybody a reason to expect a stress-free afternoon.
