"It matters because we play in a division where all of a sudden there's rain, there's snow and it's different. I think guys that have big hands can grip the ball better in those environmental situations," Jackson said.
"It's a little bit useless as a measurement," Tobin said. "When you shake a guy's hand, you know whether or not if they have a big hand or not."
Goff had an opportunity to chime in on the hand-size debate on Thursday and he defended his mitts from the scrutiny.
"I've been told I have pretty big hands my whole life," Goff said. "I heard I have small hands yesterday, apparently. Naw, I've never had a problem with that or expect it to be a problem at all."
North Dakota State's Carson Wentz, another of the draft's top QBs, measured with 10-inch hands on Thursday. The benchmark for adequacy when it comes to hand size for NFL quarterbacks, though different clubs have different opinions, is said to be in the 9-inch range. As such, Goff's hands won't necessarily be considered small or a liability; they'll just look small compared to those of Wentz.
In one of the few games Goff struggled in his college career, he completed just 3 of 6 passes for 11 yards in a rainstorm in 2013 as a freshman against Oregon. Later that season, Goff was confronted with stiff winds in a road game at Colorado, and struggled in a 41-24 loss.
Another of the draft's signal-callers, Penn State's Christian Hackenberg, also measured with 9-inch hands.
Goff and Wentz are expected to be the first two quarterbacks chosen. In which order they're picked, however, is a matter of greater speculation. Hand size, of course, will be only one of many determining factors, but it's a category that Wentz won -- well, handily -- at the combine on Thursday.
