I'm far from a experienced gambler, but these 2 bets look to have some good value:
Player to score first in the game will have Odd Number Jersey +250
Player to score last in the game will have Odd Number Jersey +250
Here's a list of players with odd number jerseys in this game: Greg Jennings, Jordy Nelson, James Jones, Andrew Quarless, Tom Crabtree, Ben Roethlisberger, Mike Wallace, Heath Miller, Matt Spaeth, Mewelde Moore, Isaac Redman
Granted, both kickers have an even number jersey, but I think that's a bit more likely to come into effect for the player to score last in the game, which is why I'm looking more seriously at the player to score first in the game bet.
