I think we've reached that point in time where we truly call it "positionless basketball." Self talks about it. That impresses me because I believe he has a feel for the direction basketball is going. Sometimes I think it is easier for us old timers to assess where basketball has come from. When I was young the game was all about positions and you recruited to the expectation of the position no matter how bad you had to recruit. Spin forward to today, and most coaches try to find ways of getting minutes to their best players, even if it doesn't fit into the traditional positions. Self definitely knows this.
I'm thinking to myself right now... "what defines a guard?"
I think I'll look at it from two perspectives; guard-like attributes and big man attributes.
Guard-like attributes - obviously first, ball handling ability... ability to face pressure (including double-team), ability to go where ever you want to go, change direction, crossover, dribble drive. Seeing the game is important... being able to setup other players, run offense (point guard skills), proficiency at the pass, low turnovers, high assists. Shoot the ball, mid range to the long ball. Finish drives to the rim. Speed. Defend the drive.
Big man attributes - finish in the low post, back to the basket, rebound, defend bigs well, seal off, hold ground, block shots. Have size... height, girth. Play above the rim.
For any player to make it on a Jayhawk team he has to have some of these qualities. Most players will have some attributes from both of these groups. Usually, one side will be dominant. And one thing is for sure, a player has to have a certain level of ball handling to be considered a guard.
I see several players on our current roster I could tag with either position... so for the sake of creating hype, it works well for me to call it "an all guard lineup" or "4-guard lineup." Some of these lineups might lack girth, but many will have height regardless what we call it.
The NBA has had plenty of bigs that can be called guards, from early on with Magic Johnson, who always was considered a guard, to Kevin Durant, who might be considered a forward but usually plays like a guard.
