Lots of folks are picking on Donovan McNabb for not knowing that NFL games can end in a tie.  Turns out there are a lot of players who didn’t know a game could end in a tie.  Guess what… it’s not the players’ fault.  It’s the coaches‘ fault.  The coaches are supposed to know the rulebook front to back, and they’re supposed to impart the required knowledge onto their players.  If a receiver comes from college, where they only need to have one foot inbounds on a reception, he should probably know just from watching games on TV that he needs both feet inbounds in the NFL, but it’s the wide receivers coach’s job to make sure he knows it.  If he admits later to not knowing the rule, and he’s not lying, it’s the coach’s fault.  End of story.
