Jackson said hand size -- a trait that draws a lot of attention when it comes to QBs -- does indeed matter for signal-callers, citing the rainy, snowy weather that QBs will encounter when playing in the AFC North.
Why is this a potential hint into his QB preference?
Wentz, who was measured last month at the Reese's Senior Bowl, has 10-inch hands, more than big enough to suffice for an NFL QB. Goff, an underclassman, didn't take part in the Senior Bowl, so his hand size is a mystery that will go unsolved until, presumably, tomorrow, when he's due to be measured at the combine.
Unless he defies expectations when paw meets tape measure, it won't be a favorable development for Goff, and it could push Jackson into Wentz's corner, if he's not there already.
