I hate to do this, but I'm going to have to pull a Randy here.
Please show me where I said I thought Kobe was too dumb to offer this response! I said your assumption was dumb. The reply couldn't have been scripted because the question was asked on the court. That is a dumb assumption.
Personally, I think Kobe is definitely savvy enough to come up with that quote on his own. Especially after this past year.
