Because the "ärt" of Quarterbacking isn't as big as deal as QBs who use their feet as much as their arm. McVay wants a 1 week rental and Stafford will be good to go after the bye. Wolford while not being a good QB knows McVay so the learning curve is less. Shanahan is doing the same thing w/ Purdy (round aboutly.....) by not going to Darnald and I know he's a better QB than Wolford. Coaches think week by week in these situations. We try to see a few weeks down the road and miss the forest because of the trees. But in the NFL things change week to week, so they have to see how the lanscape has (or has not....) changed. But it's the reason coaches are offered millions of dollars, and we havent been offered a dime for our knowledge base. Sorry but it's reality.
