The rapper-producer brought his 5-year-old to the Tampa Bay Buccaneers game Monday at Raymond James Stadium, where they hung out one-on-one with none other than the G.O.A.T himself inside their luxury suite before kickoff.

Check out the video ... looks like Saint helped TB warm up by throwing a ball back and forth, while papa bear filmed. Not just that, but Tom chopped it up a bit with the kid, too.

Super cute moment, no doubt -- and you can tell the Bucs QB knows a thing or 2 about talking to kids. He does have 3 of his own, one of whom he references here.

According to Tom, Saint is just like his middle son, Ben, who's apparently pretty creative. Ye makes a suggestion that gets a chuckle out of TB ... who knows, they may schedule a follow-up play date after this!

All in all, a very cool daddy's day out with at least one of his brood -- and peep the music Ye put on this video. It's the Sunday Service version of "God's Plan" ... another sign he and Drake are totally cool now.

No sign of Ye's other kids here, who might have been back on the West Coast with Mom ... even though she was a little busy herself.

As you know ... Kim went out to dinner Sunday night with Pete Davidson, where they had their own little booth ... and where PD was flashing some bruised skin.
