they can if they exceptional enough.
The three you mention are interesting and could easily be argued for and against.
Both Richo and buddy are/were capable of kicking great goals, particularly on the run from distance, but did/do let themselves down with easy set shots at times. Does other attributes such as their athleticism and marking make up for it? yeah, probably.
Buckets was a very good mark but probably didn't kick the miraculous goals the other two were capable of, but he did work hard on his kicking and finished his career as a reliable kick. A grade? hmm there abouts.
But back to foley, does his have elite attributes than can make up for a weakness in the most important aspect of the game?
Borderline for mine, and combined with inability to stay on the park id say an A rating is a tad too generous.
Ratings are very subjective, of course
