As a bears fan I like that he hung them up now.
As a football fan, he hung them up because no one wanted him. He wanted too much from the bears organization and they werent willing to bend for a player way past his prime.
Sad to say, but he made his bed and he laid in it for this retirement. He could've taken the deal that was offered and atleast played one more year. He chose to be greedy for his worth and now he is retiring.
I'm still an Urlacher fan, but I'm also a realist.
