I've been a fan of the game for a long time now, and during my 20 or so years as a serious fan (and amateur player), I've collected a little bit of knowledge. In order to succeed in today's NFL there's a few things rookies should know about, and probably do, but this is more for my fellow fans who wanna know what it's going to be like for the rookies. 1.) Get comfortable. If you're comfortable in what you're doing, you'll be able to do it. Don't be worried about making mistakes, they're going to happen, but make new mistakes each day you're out there. 2.) Know your surroundings. Learn about who's coaching you, learn about the franchise you're playing for. Be informed. It makes small talk very easy, and will go along way. 3.) Embrace being the new guy. Veteran players are going to mess with you and give you little jobs, do those jobs to the best of your ability and accept it. Don't be a smartazz and make the proven players resent you. One day it will be your turn to haze the rookies. 4.) Stay out of the training room. You're only suppose to be in the training room for one reason, and if you're constantly in there guys will assume you're soft. Don't try to be sneaky and beat the heat by acting hurt, this is not a good way to start off. 5.) Fight for every rep. Let your teammates know you're serious about being there. Reps are limited, so make the most when it's your turn. I think if rookies followed this checklist, more would have success early. I'm almost 100% sure the NFLPA does give these guys this same info or something very similar, but they don't seem to make it public information for the fans to see. So here ya go.
