After reading that article, I'm actually pretty enthused, if not excited, about this pickup. If you are just replying, and didn't even read what was in the OP, you should read it:
In December, Williams injured his right Achilles’ tendon and was cut by the Cardinals, and John Schneider recently signed him to a two-year $1.2 million futures contract worth $555,000 in 2013 and $645,000 in 2014. “We got him,” Schneider was recently quoted as saying.
“It’s insane. It’s an absolute crime,” Cardinal’s Bertrand Berry said back in 2010 when asked how NFL teams failed to draft Williams. In the same 2010 interview, Larry Fitzgerald said that Williams may eventually replace him as the #1 receiver on the Cardinal offense. ”That’s a good thing to hear coming from a guy like that (Fitzgerald),” Williams said. “I’m learning from him every day, how to pick his brain and run routes like him and the different techniques he uses to get open.” Derek Anderson compared Williams to Josh Cribbs of the Cleveland Browns. ”Josh was one of those guys,” Anderson said. “He’s not a great receiver, but he’s a great athlete and probably one of the best football players I’ve ever been around.”
I know this doesn't mean much, and he was an undrafted receiver to begin with.... but this is promising. And we all know the terrible situation in Arizona- combined with John and Pete's knack for finding talent, we could have a case for something here. I'm not counting on it, but I am optimistic.
