I fail to see the drama here -
Grob was given three years to do a job, he failed each of the three years. At the end of year three his contract was up for review.
If Bobby wants to point fingers lets point out that Grob possibly cost the Chiefs thier best shot at the super bowl in years and drug down the most productive offense in the NFL with him.
Since when wasn't he subject to real-world expectaitons?
I'd like to see what Bobby does when the waiter brings him a soggy pork chop just once let alone three years in a row.
