NFL2k: the dawn of a new era of video football. Some problems were evident but nonetheless a great new beginning.
NFL2k1: Online console football on the Sega Sports Network
Unfortunately out routes were MONEY grrrrrrrrrr
NFL 2k2 : Transition phase. Defense was crazy on Xbox and PS2, but not so much on the dreamcast. One thing it had over the last two installments 2k4 and 2k5 was defensive speed. The DB's were horrible at times though. They would jump way before the ball even got close to being there
No pre snap blitz animations. But the defensive line was better than because they got off the snap fast like they SHOULD. This is an advantage it has over 2k4 and 2k5. No gang tackling though and sometimes the running backs grrrrrrrrrrrrrrrrrrrrrrr.
NFL2k3: Best zone drops by defenders, here guys actually dropped to their zone area and slid and spyed the WR's when doing so although even here it could be better. The DB's when you ran cover 3, didn't just turn their back to the QB upon the snap. They started with a backpedal and watched the nearest receiver. Running game was great, the intermediate and short passing game was pretty good albeit the deep passing game was kinda mehhh. Good presnap blitz animations, however blitzing was bad. Could not get a sack to save your life against the A.I. Of if you could it was hard as hell. Playing defensive line it was hard to get in. In this regard it is better than 2k5 where guys play defensive line and don't get touched at all. Shoulder charge was a problem though. People used it to gain speed and Alstott and Bettis were promised at least 5 yards everytime you hit it and with no two player tackling, the balance of the game had began to shift.
2k4: Crazy running game, super blocking linemen who suplexed, clipped tackled defenders. Bad tackling. All angles were bad angles. Running game on steroids. Backs in the flats for TD's, screens for TD's. This game was WIDE OPEN on offense. Turn on dime physics ect. Defense needed alot of help. No pre snap blitz animations to signal blitz. Blitzing was OK.
2k5: Running toned down, but passing gone wild, especially deep passing. Defense needs help again. Blitzing is bad
especially the outside blitz. Only Patriots have good pre snap blitz animations QB scramble madness, no QB spy, defenders do a bad job of zone dropping, short and intermediate passing game on offense declined everything just deep. There is no way you should be passing deep against 7 man blitzes, but here it happens all the time and most of the time you can get a TD off of it. The blitz should force you into intermediate and short passing game
DB's are about like 2k2 and 2k3, Premature ejumpulation.
By the time we get to 2k5 the offense has seen a SURGE and the Defense is lagging behind.
This is not to say the offense can't use some work, because it can, but the defense needs the most work.
