It was definitely enough time, but if Derrick stays with Chennault, he should be able to slow him a bit. It looked like a completely botched defensive assignment, but I think the mindset was to slow him down and force 'Nova to have to beat us with a potential off-balance Rotnei Clarke type miracle heave rather than risking putting them on the line. Under the circumstances it didn't work, but if every dribble takes a second as you mention and you can go from baseline to baseline in five dribbles, the thought process of slowing them down a bit makes sense. Didn't work even remotely, but makes sense.
