After watching Rudy and Sticks (and DD early in his career) struggle to create their offense a lot playing the 3 against smaller and quicker wings, I personally think it's better for tall wings to play stretch four in college and use their skills against bigger players to gain a better advantage. Rudy is an NBA 3, but he's going against players his own size in the NBA and has been a better offensive weapon there than he was here (paint was too crowded to post up with Boone, Armstrong and Adrien at the 4-5). Duke has done that in the past with guys like Battier, Dunleavy, Deng and Singler playing a lot of 4 even though their NBA position was at the 3. A lot of other examples out there too ranging from studs to role players (Durant, Gordon Hayward, Gomes, Matt Barnes, etc.).
