How many guys are in the "will play PG, but isn't a PG" camp? For Wichita State, I think Baker is definitely a guy that will get minutes at the position, but he is definitely a SG. Good enough ballhandling skills to bring it up against Louisville anyway, but he's wired to shoot first and pass second. Cotton may play PG some this year as well for a minute or two a game.
Outside of WSU, it seems like the biggest guy I can think of is Walt Lemon Jr., but there are surely others. It seems like coaches with 3 or 4 guard lineups tend to have less of a set PG and more of a PG by committee approach. Several different people bring up the ball, depending on what the defense does and if the main PG is resting.
