In browsing around, I foundthis interesting take on Matt Barnes from NY fans.  I hadn't realized he spent a few months in a Knick uniform.  I suppose it gives us some insight.

Some of the better mental images:

(on his crack-induced energy)

For example, on defense, he'll just randomly swing his arms in every direction possible

(on why he got cut from that god-awful 23-win team)

It clearly wasn't basketball related ...  It had to have been something off-court....  Perhaps, we decided, he had attempted to kidnap Larry Brown and sell him to passers-by for 39.95 with which he hoped to purchase crack.
