It's GREAT to be Dak Prescott ... dude just showed off his shredded bod by the pool Friday -- and just hours earlier, he made things Instagram official with his smokin' hot model GF!!
Oh, and he just signed a 1-year, $31 MILLION deal with the Dallas Cowboys this month!!!
Yeah ... jealous yet?!
Dak was with the Dude Perfect guys for some trick shot work by the pool this week ... and while we're sure the throws were fun -- DO YOU SEE HIS BOD!?
The 6'2", 238-pound QB has clearly avoided the quarantine 15 .
