Tie game and you choose to iso at the 3 point line for game
Are you that intent on pushing your dumbass agenda that you can't use your brain and see that it was the best shot possible, given how the play unfolded?
As the homie said above, the play was clearly designed for Jaylen, but once he was knocked to the ground, Tatum had to freelance. He couldn't drive left because Mitchell was right there closing off the lane, and it would've been pointless for him to go right when there's minimal space to work in.
It was a great decision by him to square up Agbaji (given the dwindling shotclock) and even better execution. It was an incredible shot.
