I don't know what you normally play, but if you just want to have something on it to validate your hunch if it does happen, $10 is nothing to risk with a nice 105 return - or some variant of that based on your normal amounts.
The first expectation is the Vols are going to have to come out with a C type effort. That is very possible because they are off 3 really big and 3 really tough physical games. If they don't come out flat then my respect for Pruitt will go even higher because it is going to be difficult to get them to play their best this week.
The other thing is the Charlotte will have to play much better on O than they have vs CUSA teams. Like last year when we saw UMass or two years ago Ohio have some success on different UT teams, but similar in terms of Vols personnel, those were teams with alteast decent offenses UMass and Ohio. The games weren't high scoring because I don't think a mid-major of that caliber with a good O is going to have a ton of success vs pretty much any SEC D, but they had enough to execute and make some plays. I'm not sure that Charlotte has that ability based off of what I have seen. They are kind of pedestrian O. So we are going to need some higher level of play out of them.
Charlotte's D has a chance to make it a game. This has been a pretty surprising unit from where they have been in recent years. Now last week, SMiss kinda had their way with them except for on the scoreboard (outgained them by 200y and lost due to turnovers (pick-six) and stopped on downs in CH territory plus missed a FG). Then there is the App St game who blew them out, so it isn't like they are just stonewalling people. Never the less, Charlotte has benefited from playing well vs some weaker offenses and has performed better than expected against some better ones. If they can keep that up and even elevate their play for a game like this, their D may give them a shot.
Naturally it is a tall order, but not out of the question.
I'd say throw something on it to satisfy your curiosities that you wouldn't mind losing, almost expecting it the ML to lose and hopefully the ATS covers as an insurance plan.
