Fresno State enters the 2012 football season fairly lucky in some respects: They have their QB situation nailed down. Junior Derek Carr will be starting. Period. Carr, who threw for 3544 yards and 26 TDs last season, may be the best QB in the MWC heading into the next season. He has a cannon arm and can move well (4.6 40 time).
Next on the depth chart is redshirt freshman Marcus McDade. After Carr leaves, or in the event of an injury he is the most likely to take the reigns. He is both mobile and extremely strong-armed, and has decent size to boot (6-3, 214 pounds). He has experience in a spread offense like the one offensive coordinator Dave Schramm will be running as well.
Sophomore quarterback Greg Watson will most likely be a career backup. Recruited out of high school as an athlete, he is somewhat undersized at 5-11 and 200 pounds. He lacks McDade and Carr's arm strength, but he does have considerable mobility.
Last is incoming freshman Myles Carr. He has no relation to Derek or David Carr. His arm strength appears to be average, as is his size (6-1, 200ish pounds). Like the other two, he is fairly mobile.
