If you're one of them, you know who you are.
If you're not, you know who I'm talking about.
There are some people who are fans of themselves first, and the team second.
Let me illustrate.
There are many fans, myself included, who worry about the Rams' decisions to select Tutu Atwell, while passing on the chance to take Creed Humphrey (or Josh Myers), and then to seemingly elevating Brian Allen to the starting lineup at center. It is entirely rational to look at Tutu and see an exciting, but potentially limited player at a "luxury" spot, and then lament seeing Humphrey and Myers (top prospects at a perceived high need position) securing starting jobs in KC and GB. Couple that with Allen's less than stellar history, and it is entirely reasonable to question whether the Rams might have made a mistake.
There are those, however, who don't leave it at that. There are those who will insist that the Rams blew it, even before any of these rookies plays a down in the regular season. Among those fans, there is yet another subset... those who will actually hope that Tutu and Allen fail, and that Humphrey and Myers succeed, so that their prognostication will prove correct. In other words, there are some fans who place "being right" above the teams' best interests.
Don't be that fan.
