OK I'm an NFL noob in Australia and the televised game is Bucs v Skins. Tell me who to bet on, I need some gamboooool fun. The lines on pinnacle ATM are...

Bucs:
-5.0 @ +120
-4.5 @ +115
-4.0 @ +109
-3.5 @ +104
-3.0 @ -121
-2.5 @ -145
-2.0 @ -154

Skins:
+5.0 @ -135
+4.5 @ -129
+4.0 @ -122
+3.5 @ -112
+3.0 @ +107
+2.5 @ +129
+2.0 @ +137

Also any input on the total points line would be fun. Also, what happens if I take the Bucs at (-3) and they win by 3? Do they just pay out half the ticket? TY for any input.
