I have both of these QB's and have the same dilema.
I can see Hass throwing for 200 yards, 1 TD and 0 Int's. Based on our league's scoring, Hass will positively get me 10 or 11 points.
I see Warner throwing for 300 Yards, 1 TD, 2 Int's. That would be only 8 points. Sure there's potential to get 2 TD's and less interceptions, but not likely.
Let's see, slam dunk of 10 or 11 points with Hass or probable 8 pts with max upside of about 14 points with Warner. I'm playing it safe and starting Hass.
