Help me understand Ohio St line

Capping this game and I have this line at -13.5.  I don't get how the line is only 9.  Also I have the ML at -600 at least Pinny has it -340 again way off. 

I don't get it.  Can't see any way Miami hangs here against the Buckeyes.  The ML is a no brainer even if you don't like those odds but -9 is also a gift.  Only way Miami covers 9 is a backdoor cover but I don't see that.  Buckeyes are gonna step on the gas from the get go and won't let up.

Ok mr 13..... osu will come out super rusty... canes or no play...

Time off is exactly what Ohio State needed 

Ok...

Ok, trust your Power Ratings Sir. Maybe , Miami hangs in early and wears down late. I really wish we knew the outcome and play by play.

How's that time off?

Well at least now you can see it right????

hindsight now, but excessive time off is bad....... 

Hindsight what.. Only a dummy would have played osu -9.5 or 13.5... 

Nope...
