Diversity is the key to surviving downturns.In the course of one week, the Cowboys lost cornerback Adam "Pacman" Jones to an indefinite suspension for an off-the-field incident and quarterback Tony Romo to an injury for four weeks. However, despite these losses, the Cowboys have strong assets in wide receiver Terrell Owens and running back Marion Barber, who has struggled as of late but is solid in the backfield. In addition, when the team most needs a boost, it is getting an infusion of new blood. This week the team traded for wide receiver Roy Williams. The Cowboys sent a first-round draft pick, a third-rounder and a sixth-rounder to the Lions in exchange for Williams and a seventh-rounder. The move should immediately help the team weather its recent on-the-field and off-the-field storms. Terrell Owens has been in a slump, as he has drawn extra attention from opposing teams' defenses. Williams should draw attention from the Cowboys' opponents, opening up T.O. more. The addition also creates a potential long-term solution at wide-out for the Cowboys. T.O. is a special player, but who knows how long he will want to play or how long he will be able to play? Williams is younger and should help the Cowboys over the short term and long term. He is 26 years old and in his prime. Diversifying a team is one thing. Diversifying a portfolio is another. Today I am looking at International Business Machines ( IBM).
