It's seems ridiculous but...

1) We're in a pandemic season filled with chaos.   A stunt like this would be too easy to pull off in 2020. 

2)  TSUN wasn't going to get into the CFP, so why not try anything to beat your rival? 

3)  Is Harbaugh desperate enough to try this?  I think he is.  This might be his last chance to beat OSU.  Why not try everything and anything?

I'm not a big fan of conspiracy theories, but in 2020 I think we need to be careful with this game and expect anything.  If we see Joe Milton starting and playing like he did vs Minnesota....?  If there's a walk-on at QB or a RB playing QB, then we know Harbaugh didn't sandbag anything.
