I think you all are focusing on a minor consideration for McVay.
I think McVay's main focus for back up QB's is to lead a scout offense, imitating upcoming opponents. I think that's why Wolfy and Perkins are here, because they offer different type QB styles for our defense to go against. They may be good imitators and McVay likes that. Before this year, most of us would have said losing Stafford means sure losses anyway and maybe McVay feels the same way, so why not have back up QB's that can help them win during most of the year. I know that right now with Stafford injured our focus shifts toward incompetent game day back ups. IF we spend our 2nd round pick next year on a back up QB, that will be a lost year too, imo. We need help on the Oline more than anything, to help Stafford stay upright....
