Possibilities as I go through them in my head:
Sark sucks at evaluating QBs, our QB situation is a result of that.
Likelihood: Low. Many big programs wanted these guys.
Sark is as good at evaluating QBs as he is at calling plays (best in the nation). He just got unlucky with these three guys, and they actually suck.
Likelihood: low-medium. It happens sometimes (remember Aaron Corp situation)
Our surrounding talent sucks, making the QBs look bad, but its not their fault
Likelihood: Medium. Our WR are pedestrian, our OL is subpar, our RB are below par. Still, some things just look bad (Troy running into two defenders repeatedly, locking on)
Troy looked bad because of the weather, he is actually good
Likelihood: low-medium. We only had 3 points of offensive production, as opposed to ASU's 17 points (if i recall correctly). He made many mistakes that should not have been caused by the weather.
Our offensive scheme just sucks in some way
Likelihood: The highest out of these. All of our QBs suck, we are very predictable. We don't utilize what works, we just do random shit (lindquist is on the field, What are they going to do I wonder?). Our QB's look like total scrubs. They might not be all world, but there's gotta be a better way. It doesn't even seem like we can even utilize the field past the line of scrimmage. It's not just been just one QB, the offense feels sucky with all of them.
