For those of you who think this is a good signing (I admit, I liked it for about 1 minute, until Comrade Brosef Stalin talked some sense into me), lets look back at Mr. Benson's career in the NFL.
In Mr. Benson's first training camp, his teammates hated him so much they tried to injure him. Fox Sports Jay Glazer (who gets every scoop in the NFL) said that 10 Bears Defensive players told him they were trying to injure Cedric.
Mr. Benson did not earn the starting job, then blew out his knee (at least he has that in common with every Bengals running back).
The Bears were eager to make Mr. Benson the starter (due to his $35M contract), but Cedric was injured by "running into Brian Urlacher" during a routine scrimmage. The injury was "not serious" and he missed the entire preseason. Thomas Jones was the starter again.
In 2007, the Bears made Mr. Benson the starter. He sucked. He averaged 3.4 yards a carry, so did Adrian Peterson. No not that Adrian Peterson. Then he got arrested twice. Now he is a Cincinnati Bengal. Wonderful.
