Even if you don't believe in the Pinny "lean" it's wise to play for the middle on the semi-key number of 4, at these prices. If Philly is up 3 late, and Seattle gets a TD, you cash both !
Why bet the Eagles at Pinny, unless the bet is so huge, a dime doesn't dent it ? It seems a strong indication that Philly is the correct side. The people hitting it hard aren't Joe 6-pack with $50 on it.
With situations like this, players playing for the middle usually send their funds to Pinny, and win the SIA side of the bet. I say just play the SIA side, and don't pay Pinny.
Even if Pinny is pure action, the indicators strongly suggest that Philly side is at least a 53% bet.
