I disagree. I don't think it's silly at all. Not in the slightest.
I watched all of Archie Manning's career while he put up similar numbers and his teams NEVER reached the playoffs.
But, my point here is that whether we make the playoffs or not, it's typically more than one player.
Point is, if we don't win next year, it may or may not be Sam's fault.
And to just take a position before that happens (i.e. no playoffs=it's Sam's fault-period) seems like making up your mind who's fault it is, before it even happens.
