I'll go with a variation on the old Parcells line that you are what your record is regardless how good you think you are.
In three years Sammy has averaged around 12 games, 50 catches, 800 yards and 6 TD per year.
Blame it on injuries, blame it on the QB...it is what it is.
I'm fine with not picking up the option. In a perfect world, Sammy actually has a stud year and we work out a deal.
