Profile of the popular actor now starring in the hit TV show Modern Family. Early on, O'Neill's career was a series of "almosts." He almost became an NFL linebacker, and he was almost cast as Sam on Cheers, but Ted Danson got the job. O'Neill finally broke through when he landed the role of the obnoxious but lovable Al Bundy on Married...with Children. Now he's a solid success with countless TV shows and films under his belt.
