Thanks. I'm not good at all scouting from the "eye test" so all I can do is draw on Pomeroy or Torvik to help me understand what I'm seeing. You could just as easily develop a counternarrative like this: OU is good at not turning over the ball so that negates pretty much all of VU's defense. Since OU takes care of the ball, they can take advantage of their eFG%. Vanderbilt isn't great at rebounding, probably not good enough to punish OU's glaring weakness.
See why matchups are tricky?
