Mac has 1 obstacle left.
1. He's not major D1. Mac won that debate.
2. He will not play or get very little PT at Georgetown. Mac won that debate.
3. Surely, he will never start at Georgetown. Mac 3, doubters 0.
4. No chance of him playing past college, not even the Euro league or G League. 4-0 Mac.
5. Well surely he can't actually ever step foot on an NBA court or even score. 5-0 Mac.
6. Last one up for discussion. He will still not make an NBA team for a full regular season contract. After going 0 for 5, if you are a doubter, it's probably best to stop now down 5-0. The odds of you getting it right on try number 6 are low.
