He hasn't played well in high-pressure tournament games, this year or last, throwing up bricks, turnovers, inability to get in the paint, missing defensive assignments, taking way too long to get up the court, starting some plays late and out of synch with the clock, fouling at inopportune times - and his turnovers defy explanation, coming at the most strange and critical moments.
I don't believe he's quick enough to compete with guards like those on Alabama.
Maybe he's reached his ceiling?
