I don't know what the drugs in question were. Googling usually turns up the specifics of the violation but nothing pops up on this one. There were a ton of hits from a few seasons ago about Henry getting shot up before every game as he continued to play on a broken leg. 149 yards two weeks after the fracture and 169 yards a month after. That's what I'd like to see replace Curtis in the short term.
I don't want Chris Brown at all. He's got a lot of talent but he's very injury prone and that's only going to get worse as he gets older. Some team may get lucky with him and have him put together 2 or 3 injury-free seasons in a row but the chances of that are really low.
