It all really depends on how difficult you want youre experience to be. I personally don't read any thread that contain spoliers in them cuz that just takes the fun out of it. I also, when playing, put the game on mute unless Im in game(where I supersim btw). But I mute it that way I dont have to listen to Adam Scheffler ramble on about draft prospects. I also set it to where the CPU scouts for me.
Like, I won't see a name in the draft until draft day, and whatever is scouted is all I got to go by when I draft a player. Makes it much more challenging, cuz if you scout on ur own its really too easy to get star players, and especially if you're reading these boards.
Honestly, I'd advise staying away from the boards period if I were you. It's pretty much what I've decided to do, cuz ppl give out too much info, even with just the title of the thread.
Just play around with the game. Start a season with a team to get the hang out it first. And to make it more challenging, I started my season with the Panthers after the 2008 draft, so I didnt re-do the draft like most ppl do. The game is great if you allow it to be. It's not very fun and you can lose interest if you read all the spoilers, and scout only players that are compared to great NFL players.
