Need help maximizing hedge

[DeluxeLiner]

Minnesota Vikings ML +110 Dallas Cowboys ML -465 Tampa Bay Buccaneers ML -350 Chicago Bears ML -335 Arizona Cardinals ML +145, $50/$471.80

Arizona Cardinals ML +145, $50/$72.50

These are my two bets. It seems that all my teams are going to win in my parlay. The Arizona game is later and I am not so sure about this game and would perhaps want to hedge it out. What is the best way I can hedge my bet here? Or should I let it ride?

3 questions come to mind:

1. How large is your bankroll?
2. What's your estimate of Arizona's probability of winning the game?
3. Why did you bet that parlay in the first place (AND bet the single bet) if you were going to consider hedging it anyway?
