How much of this should I lay off????? Philly/Saints game.

[SamuelAdamsLager]

I take my friends action. Its great because he's loaded (we're both around 35 yrs old). We usually meet up and pay a couple hundred either way but he has lost everything the past week. Heres the info.. He's paying tomorrow

He's down $2650. He took Philly $950 to make $1757 money line.

I have about $1500 on BetUs.com. I was thinking about tossing $500 on Philly. (If they lose by 5 or under I win everything)

Thoughts?
