I really think "massive influence for 20 years" is absurdly overstating his role for most of those years.
I understand, and somewhat agree with his detractors to a point. Our drafts have been below, sometimes far below expectations. That was even true in Shula's late career.
I don't believe, however, that Grier had all that much infuence for the first (roughly) decade and a half of his time here.
How many of the decisions for the last 5 years were his is debatable, and fair game for discussion, but to blame him for things that went down 10-20 yrs ago is ludicrous, IMO. Because of the cluster**** that our FO has been recently, we really don't even know who wanted what.
I'm not saying he gets a pass, but a little perspective might be prudent.
He has righted the salary cap, jettisoned players who were underperforming contracts (he has given out a couple that were head scratchers), and set us up with draft picks.
I absolutely get the arguement that he is not the greatest evaluator, but he addressed that percieved shortcoming by bringing in respected ppl for that responsibility.
