Jon Bostic and Khaseem Greene have a pretty unenviable job right now - attempt to fill the void left by Brian Urlacher. (I'm not sure why every article involving linebackers has to mention Urlacher, but here's your obligatory post mention.)
The fortunate thing is that Bostic and Greene get to develop similar chemistry that Urlacher and Lance Briggs developed over their careers. Adam Jahns mentioned this in his article from late Friday night, "Can Jon Bostic and Khaseem Greene Fill the Void left by Brian Urlacher?" (Yep, that's another Urlacher reference.)
Apparently neither does Lance Briggs, who's already looked to take the youngsters under his wing;
More important, they have a similar mentality. Neither comes off as a know-it-all, overconfident college star. They are eager to learn from those front of them — Lance Briggs, D.J. Williams and James Anderson.
Briggs has spoken to Bostic and Greene, telling them what it means to be a Bears linebacker and also leaving a line of communication open for anything.
