Look at their last few games. Which one is consistent with their point total. Are yo looking for a big total or one which is going to give you 15+ points? I just looked at Jackson and in his 5 games he has delivered 15-20 points in NPPR. Prescott has been up and down. Now look at what the defenses have been doing, TB seems to be giving up points in the teens the last five games with the exception of SF which was 8. The Chargers have pretty much shutdown two pretty good QBs in their last five games. Finally both teams have something to play for. One other thing is look at how their run defenses have been. The Chargers have been tough against the run lately while the Bucs have given up some decent yardage. The difference may be Elliot being able to run will open up the passing game for Prescott. Also the Bucs have nothing to play for while the Chargers do. I'd go with Prescott.
