Always be careful taking overs on artificial turf in bowl games, the defenses are intact and the offenses are a bit rusty and the fast turf helps the pass rush and the defense in general. Also a bit chilly and a bit tougher for WRs to make finger tip catches when it is this kind of weather.
Also take a top defense to cover the spread on artificial turf against a team that mostly plays on grass their OL is not used to speed rush on fast stuff.
SURE it does not work every wager of course not. But something to look at.
