Beanie Wells

With Cardinals running back Ryan Williams likely out for the season, Arizona's decision to trade Tim Hightower to the Redskins again will be questioned. At least the timing of it.

Williams likely suffered a ruptured patellar tendon in his right knee Friday. Tests will confirm, but it appears he's headed for surgery and a long rehabilitation period.

There already has been a lot of second-guessing, via twitter, about trading Hightower. And the timing of the deal was interesting.

With Hightower gone, the Cardinals have only four running backs in camp. Now it's three. And that counts LaRod Stephens-Howling, who at 5-7 and 185 pounds is not going to replace Beanie Wells should something happen to him.

Coaches are pleased with the development of Alfonso Smith, who was on the practice squad last year, but the team likely will add a back in the coming days. The options aren't attractive. With rosters at 90, most backs are already in camp. You can find flaws in all the ones available, from Tiki Barber to LenDale White to Laurence Maroney.
