Lets work through this logically.
1. Playing at a faster tempo per se does not give you more shots. If my team gets up a shot every 15 seconds and my opponent takes 30 seconds, we are still trading one to one possessions.
2. You say but REBOUNDING. Fair, but every team comes into the game with a goal of controlling the offensive glass. Kellie's teams generally got more possessions through a rebounding advantage (though that edge was often mitigated by loosing the turnover battle). There is nothing new or radical in saying our game plan is to out rebound our opponent.
3. What is different about CKC's system is playing a pressing defense for 40 minutes. Matt MItchell's "40 minutes of hell" scheme at KY was similar but he was not fully committed to positionless basketball or going 10 to 12 deep to maintain intensity levels.
When it works, the LVs should win the rebounding and TO battles. If opposing teams crack the LV press and shoot a decent %, that slows tempo down because the LVs would not be in transition as often and they would have to run more half court sets.
The fact that Marshall got destroyed by VT (minus their best player) should be taken as a point of concern in that better quality teams are not rattled by pressure defenses. On the flip side, CKC will have an arsenal of much better athletes than she did at Marshall and so their 40 minutes of hell should be a lot more ferocious than what Marshal could muster.
