I echo the thoughts of all those before me on here Shriiiiidy - I got into American Football (NFL) back in the early 80’s - think it was the early 80’s but so long ago it’s hard for me to recall - I know I was in single digit age years - maybe 8 or so. For me I was sent for the school holidays to stay with my mums sister and my cousins was already into it and watching it on TV - C4 I think. Anyway when I returned home and some time later came across it on the TV - I stuck with it and started to learn it. Great thing was before each new season C4 did like a beginners guide show to explain the basic rules of the game which made it so much better when watching. From there I started watching Weekend (cant recall now if it was Saturday or Sunday mornings at 10am) highlight show of the previous weeks results - the show was called ‘Blitz’.
Then later on Monday nights C4 had extended highlights of the best games from Sunday - easy to avoid results back in the day as there was no internet or anything so it could almost have been live while watching. Then C4 in my latter tween years I think may have had a live game on and at some point C4 also started a fantasy football game in conjunction with its magazine show (you used to have to phone your team entry in via premium rate phone line and did transfers the same way throughout the season - cost a fortune, but I loved it).
I also used to buy a newspaper magazine (then later subscribed to it) here called First Down that kept me abreast of things in the NFL stateside plus it did its own fantasy football game you did by mail so naturally did that. Their first prize was a trip to the Super Bowl and one year I never forget I finished 3rd in the whole country and worst thing was my buddy worked out if I left my team alone in the third and final trade window and didn’t make the trades I did I would of won. Even worse there was nothing for third. 
Now in later years when the internet came about I was late to get it myself at home but when I finally did I never looked back finding the NFLUK forum and doing their salary cap fantasy game. I also found out about Super Bowl parties the NFLUK Forum (London based) hosted for free in London to promote the sport and started to attend them - I got a random invite the first ever one they did - no idea what it was but as I used to go on my own up to London for Super Bowls just to be around other people who liked this sport as much as me so always planned and went to individual Super Bowl parties before then put on at bars / restaurants (that had a cover charges) so thought I’d try this freebie I had been sent tickets for. I took my closest work mate at the time who I’d been getting into the NFL by doing fantasy games and letting him kick my butt at Madden… any way it was off the hook - hosted in a nightclub, free pizza, huge screens loads of genuine fans off the NFLUK forum and guest appearances by ex players and a live music group in concert pregame… I said then and there that was the kitty and by hook or crook I managed to attend every one for the next 8 or so years - sadly (and I don’t know why) but last year was the first year the NFL here in the UK did not put that party (called Super Bash) on.
However if you would like to know more about these parties I did do a thread on NFLUK some years ago to try and record the history of them I’ll find a link and add in here: Super Bash History Thread - NFLUK
Back to fantasy - also with the advent of the internet I started doing the fantasy games on NFL.com and after a year or 2 got fed up of being in leagues where people give up if doing bad - winning them was like a hollow victory so I decided to make my own leagues up but came up with rules to try and get competitive people in my leagues. I came up with angles like a USA v UK league and an International league to show Brits knew as much if not more than Americans on there sport (the first league) and later the International league was to give people pride that they was repping for there own nation. This worked and then from doing those games I started to run fantasy games for money with personal friends and work colleagues, this spread to friends of friends and finally I started advertising online like NFLUK. People played with me for years and back in 2014 after a few years of trying to join other peoples that never came to fruition I decided to try and organise my own live face to face offline serious league - to make it so decided to make it for a fair stake and that is how I came up with a live draft £100 money league that many of the people on this site joined.
However NFLUK did not want its site associated with gambling or any such things so one of the guys from my Original league created this website for that purpose and I changed the name to reflect the community we have here now - TFP.
From that league many of the guys have formed friendships and other leagues have spawned. It really has helped me make new friends that share the same passion for this sport I love.
Also over the years as some games have stopped I along with my friend McBear have carried on and run our own games via the internet and e-mail to keep them alive (like the now defunct First Down fantasy football game that went when the paper was wound up). We do some things different though and have tweaked it to work for us with different player values and have a game to incorporate the whole season (not just the regular season as FD’s game did).
Here is a link to the players list McBear and myslelf made up and priced up for this current season: Gridiron Players list 2016/17
& here is a link to the game rules: NFL FANTASY GRIDIRON (AMERICAN FOOTBALL) 2016/17 (Season Long Rules)
Feel free to take part your self next season… more the merrier. 
Sorry about that but I just couldn’t stop myself as I think fantasy football has increased my enjoyment of this sport massively and helped me make many new contacts and friendships through playing fantasy games.
