[RudeboyOi]

hi im fairly new to sportsbetting

$200 to win $500 teasing 6.5pts

KC +10.5, bears +7.5, browns +7.5, eagles +3.5

my friend advised me that crossing the line is bad

the eagles line was -3

but how can this be bad?

if i was only up by a FG id lose

but now i can be down by a FG and win

any advice much appreciated in advance

thank you
