Grier has been substandard until last draft record-breaking Waddle, Phillips and Holland, hopefully the next Ed Reed. Eichenberg is raw but shows promise too. Can't ask more of a draft than that. His FA signings this last season weren't nearly as inspiring until Duke and Lindsay..but those seemed to be out of necessity.
As this is an exercise in mental masturbation since Grier is not going anywhere, I'd say "hypothetically" he's done enough to deserve another year provided there is close scrutiny.
