Jones' handspan is 9.75", which is bigger than Brady's 9.38"...so Jones can at least somewhat grip the ball in cold weather/high winds.
For reference, here is a list of the largest handspans in the NFL as of maybe 6-7 years ago (old article that mentions McNair, RIP):
Hand size is important for a quarterback. Nearly every play has the quarterback handling the ball, and small hands mean less ball control. Quarterbacks such as Drew Brees and Russell Wilson have shown it's possible to have success at a height of 6'0" or shorter if you have huge hands.

====================
We will definitely see the next 2 weeks at home vs. the Titans...and then at Buffalo for a Monday Nighter....I expect the winds to be howling for that one at least.
Nobody likes cold weather football...and I expect Jones to prepare himself as well as he can...and probably put more velocity on the ball. The good news is that it plays in our favor as we are a defensive/rushing/ST coverage team primarily....
