Why do NFL teams continue to give troubled players opportunity after opportunity? Word from the Miami Herald is that three teams are talking to Chris Henry, the former Cincinnati Bengals wide receiver whose arrest statistics are probably better than his receiving statistics. This is a player that can't even play in the first 4 games of the season due to a ban for personal conduct (read: arrests).
I am sure whatever team does sign him -- and I am sure one will -- they will say all the right things: "we're giving him one last chance", "we're helping him straighten out his life", etc., etc. etc. while at the same time putting all the necessary clauses in the contract in case they do mess up again.
Michael Vick (no explanation needed) will also wind up back in the league.
The NFL head office has done a better job of improving the image of the league, but as long as championship-hungry owners continue to ignore past histories to sign a player who may help them win the league will continue along that slippery slope of alienating fans who see the league as filled with thugs and crooks. Don't believe it -- just ask David Stern.
