This game is very likely to stay UNDER the total...given the conditions & circumstances....so I would definitely hedge this situation for as much as possible. Bovada has crappy limits, so you would have to consider that...
Make sure if you do hedge this, you bet the same number...54, (which you can't get a Bovada right now)
The last thing you need is to see this game land on 54 when you bet under 53.5 and over 54....your parlay would push giving you back 35 bucks and you'd lose that big under bet you made.
