The only thing that makes sense is that 6’8” guys with the length and quickness are so valuable and rare that you take chances on long shot developmental prospects.
It took Jerami Grant until year 4 or 5 to start having an impact. Theoretically, Cody could do the same, but I'm just not seeing the mentality on his part to want to get involved and make plays. He needs to show some competitive fire, some passion for playing. He seems content just to be out there and coast.
