If Steinbach is on the board when the Spurs are on the clock, I'm almost certain he would be the pick tbh. But based on the season he's having, I think he ultimately ends up going top-10 and thus out of our range barring a complete meltdown by the Hawks. The Combine and pre-draft process will help better determine where he goes as well.
Steinbach projects as a big PF though at the next level who can play C in certain lineups. He's a skilled offensive player and an elite rebounder (statistically the best rebounder in the draft at 12.1 RPG), but a limited rim-protector due to his lack of athleticism. He has a great 6'11 frame and long arms though. Still only 19 and an excellent passer as well. He doesn't shoot the 3 much right now, but the potential is clearly there (55% 3PT% on 1.2 attempts per game). He's got great form on his jumper and is a plus FT shooter at 75%. I think he has the potential to develop into a solid stretch-4 over time, which would be perfect for us while Barnes holds that spot down for the next couple years.
