i agree the rams approach the draft through a collaborative process however human nature is such that people will inevitable disagree from time to time. someone needs to have the authority to pull the trigger when that disagreement occurs. Moreover, Snead points out below as the draft rolls on that the grades become harder to say one player is better then another thus making it more difficult to "stick to the board" and increases the chances of disagreement.
“What you do try to do is line the players up and you focus on some that definitely can come in and fill that role immediately based on their physical traits, their football acumen, and all those things. It depends on what you’re looking for,” Snead said, adding
once the draft reaches the third and fourth rounds, it’s harder to be definitive about one player being better than the next. “Usually they are of similar ability and at that point in time you might go to the player that fills a role better than the others.”
