With everything we've heard about Quincy this offseason it wouldn't surprise me to see him emerge as a leader...ideally you'd like to have one of your leaders to be the "enforcer" on your team (i.e. Sapp) that everybody respects and nobody wants to mess with...I don't see McCoy, Talib, ect...filling that role.
I wouldn't mess with Talib.
Neither would I...but the big horses on the line, i.e. Kyle Moore, wouldn't be too intimidated by him.
