Are u being sarcastic?
He's pointing out that Seahawks are -4.5/5 on the spread (depending what book you may be using), so the Moneyline odds for the Seahawks are anywhere from -225 to -240 or so. Patriots moneyline sits around +180 to +195 again depending on book.
To meet in the middle, it's basically 2:1, you'd get Seahawks at -200, Patriots bettor would get +200
Your 750 vs 375 would be more in line with what the odds are currently
