Yeah there's a lot of that - Ive noticed once a player is labelled, thats it regardless of performances for the rest of their career.
For example, some posters including myself have been critical of maccas tackling technique throughout his career, but this season Ive noticed a huge improvement on that part of his game. He is nailing them and hurting opponents which I love to see, however, not one single positive comment about it from anyone else, yet the next time he misses a tackle you can rest assured someone will pop up highlighting it and labeling him a poo tackler. I hate that about our supporters.
I havent been a grigg fan over the years but fairs fair, over the last few seasons hes been a reliable contributor that deserves his spot, this season I feel he's gone to another level. Yes hes no star and his kicking is questionable, but as an overall package he brings a lot more positives to the table.
