Greg Olsen was a first-round selection from the Bears in the 2007 NFL draft. Olsen played his first four seasons with the Bears. He played fine. Obviously, he did not lived up to the massive expectations Bears fans had of him but he still provided solid plays during his tenure in Chicago.
During the first 3 minutes of this video, he talks about his first encounter with Bears veterans, including Brian Urlacher.
Looks like Urlacher might not be such a bad dude after all...
