I just gave this thread.....players that played exceptionally well.....their rookie years.....
Okay, let's take a look player by player. Who was the #1 CB, and which of these guys played on playoff teams with a shot at it all?
Jalen Ramsey - Started and played fine, but was the #5 overall pick, which we probably won't have. His team won 3 games.
Marshon Lattimore - Wasn't the #1 CB. Played very well though. One of the few of this list on a true contending team his rookie year.
Tre White - Fills all of the criteria, team barely made a wild card berth.
Marlon Humphrey - Was the #3 CB most of the season until an injury made him a starter. Team failed to qualify for the playoffs.
Jaire Alexander - Was not the #1 CB. Team did not qualify for the playoffs.
Byron Jones - Was not the #1 CB. Didn't even exclusively play CB, and was mostly a safety to begin his career. Did not make the playoffs.
18 CBs have been taken in the 1st round since 2015, where you mentioned Byron Jones, and of your list, only two were the true #1 option. Only two were on teams that made it to the playoffs. So not only do you have to worry about the relative early ineffectiveness of these players, you have to hope you picked the right one, oh, and since you don't have Pat P. anymore, you're forced to take one even if your guy is gone, akin to Levi Brown.
That's why counting on a rookie to be our #1 CB terrifies me.
