I see flashes of Brownlee, but, man, after someone posted in this thread...Donald Emanuel might be the best comparison yet. I know most will take it as a knock on Sanchez, but Emanuel did have some decent perimeter skills and was just as slow.
Sanchez 6'9 232 and Emanuel 6'8 230. Similar stats--Emanuel ws 6 points, 3 boards in 19 mpg as a senior, 36% from three while Sanchez is 6 points 5 boards in 21 mpg and 29% from three. Emanuel played for a tournament team.
Both float on the perimeter.
