His point is that even though it looks bad - it very rarely backfires. It's a good gamble to pick someone up like that but the ones that work out are more the exception. Any recent success stories you can think of? 1-2 year players given away for nothing that end up making their teams pay
There aren't many lottery picks given up after the first year.
Robinson is the only recent one I can think of, Austin Rivers too but he should've never been a lottery pick to begin with.
Neither player is really comparable to Vonleh potential wise either.
Robinson came in the league at 21, undersize, can't shoot.
Vonleh was the youngest player in the league, 7-4 wingspan and shot 40% from 3 in college.
Austin Rivers is Austin Rivers.
