The NBA is built for guys with high upside. Reggie isn't a great athlete, is short for a center at the pro level and offers virtually nothing offensively at that level.
I feel like he's a guy that won't make a roster at the beginning of the season but could be picked up at some point due to injuries. He can be a backup guy who is more of a defensive specialist.
Not sure this will happen but I think it is possible.
