Larry Johnson a worthy risk

I keep getting mixed signals on Larry Johnson and I'm not sure what to make of him now that he's back from league and team suspension. I see that some experts say to stay far away from Johnson, but others are willing to take a chance on him. I even noticed in the ESPN Midseason Mock Draft that one of the Answer Guys took Johnson in the sixth round. Seems like a pretty big disparity between experts on Johnson, so I figured I'd go straight to the source to get your reasoning behind the positive expectations. Is Johnson really worth the risk?
