NFL2k2 is the best of the games. To note, I've played Madden 2006 and my team was the Steelers (I was CFL2006 online - CFL as in the Canadian Football League, the Hamilton Ti-Cats uniforms are "Steeler-esq"). So, I ran the bus, er, ball with Bettis and occasionally threw a short pass to mix it up and I won over 50 games straight by doing that (after a 1-19 start trying to learn this crappy game). I hate Madden because of such features as "Eagle-vision" (really) which I think was introduced in 2006 (could be wrong, not an EA anything fan).
I could NOT get away with that horrible unrealistic amateurish strategy in NFL2k2. NFL2k2 is really a true "real-world" football style of game. I play it like I would in real life but without the coach barking at us or crying to the refs (so embarrassing when they do that).
You can set up your audibles easily in NFL2k2 so you can call up to 3 audibles on offense and 3 on defense with a touch of a button. I use the 6-button Dreamcast 3rd party controller so I have the "L" option as another offensive receiver to throw to (the only game I know that uses an extra button that the standard DC does not have). My company ordered a few for me when I found that they were in a catalog we added for supplies and alternate tech (Innovation - although two of the 6 controllers did not work and I had to send them back for new - I think two are still in the box).
Think real football, time your attack and be careful of holding the ball too long. Also look one way for a sec, then look to where your primary receiver is to be and throw it at the right time or move out of the pocket if you are going to a side of the field with the pass. Always think of clock stoppage by running sideline plays if you need to save timeouts. Some teams have limited pass options in their playbook because they are based on the teams real playbook, not just a generic list of plays.
Last word on Madden (do not read unless you really want to read this):
I never really heard Madden Football over NFL 2k series from people who have played both (except now). I played a Madden" dude a few years ago that was very popular in his local town. I invited him over (being I know the guy) to play NFL 2006 (when it was still active online). I beat him in his own game (using his former console, the PS2 which he gave me in 2005). I could see his play choices on screen and learn his thinking (can't do that on the NFL2k series, the VMU is where you would see your options in secret during 2 player mode). Needless to say, he lost on NFL2k2 in which he admitted it was a really good game and then bought a Dreamcast just to play the NFL2k series - he's a huge NFL Football fan and a great classy human being and father, he broke his collarbone during tryouts with the Toronto Blue Jays in the late 1990's). He did join our community in the beginning of DC-Talk and played Q3 online against Impulse and others as "Carnage"
