WNO:Assuming you've a potential -110 payoff, i personally would not-- at least not with another minus payoff bet-- unless maybe if it's a huge bet you're worried about.
I like middling, but with the extra cushion of not having to eat vig if the middle fails: guaranteed profit in other words.
Now, if you were a 'dedicated middler'(you handicap and only bet from the outset games that don't have a blowout chance & are using the requisite bankroll & bet sizes) it'd be another story-- but if not, all you're doing is hedging minus payoffs: cutting down the size of your wins.
HOWEVER.... i would keep an eye peeled for a Money Line scalp where it still has a chance to middle, even if only at a couple of points. Hopefully your third time zone choice is a favorite, & you can now come back on the underdog ML. If not possible, you still may have a similar chance at halftime.
D.Scott: you could look for some type of bet where you can lay extra points with Philly-- though that scalp wouldn't be too big-- still, it'd be guaranteed & to boot w/ a small chance at a middle...
Good luck.
