Norbert...First and foremost thank you for the time & effort you are putting into the game. It is very much appreciated.
After reading the first 4 pages, here are the suggestions that I would like to see implemented and believe are the most important (In no order):
Formation specific depth charts (Except OL).
Have "basic settings" and "advanced settings" game planning.
Smarter individual practice settings - If I have a pure fullback, I may want to work on his blocking strength and hands, more than I do his speed and elusiveness. Same for a receiving TE, or if I have QB with 90 tech, I don't want to work him on "Passing" but the back-up I have with a 60 tech, I certainly DO want to work on tech.
Give LB's & DB's their share of sacks.
Standardize the attributes (Speed, Strength, etc.)
Many more options in play calling (Offense & Defense).
Offense: Control over the pace of our offense with no huddle/milk the clock type options, variety in shotgun formations, a "no-huddle" setting where plays are run more quickly, but substitutions can't be made (which would mean no changing formations, unless you don't mind that someone will be playing out of position), plays are chosen from a more limited selection, and players on both sides of the ball tire much quicker and a "stall" type offense that would allow the maximum time to run off between plays. Ability to set offensive blitz protection to either basic (no extra protection), moderate (TE/RB chip blocks, they go out for pass if not a heavy blitz), or max protection (TE/RB stay in to block and don't go out for pass). Situational use of tight ends and goal line formations.
Defense: Ability to: Select man or zone on defense, choose frequency of blitzes, choose man or zone with specific blitzing by situation (i.e. down and distance) would open up the defensive game planning, set defense blitz level/type (basic blitz = 1 player blitz, multiple blitz = 2 players blitz, max blitz = 3 players blitz, and also have a zone blitz), goal line formations, and double team a specific receiver.
Add more description to the PBP...a lot more if possible. Why not enhance the PBP text with coaching notes which really tells us what happened during the play (i.e. OL Murray missed assignment allowing DL Akins to get pressure on the QB. Or, FB Anderson picked up the blitz giving the QB more time).
The ability to change Max FG distance by game plan.
Expand the depth charts, like Short Yardage back, and in the play set up you could specify that you use the Short Yardage back for that play. Ability to assign a player to the depth chart at more than one position as long as he isn't already a starter at another position.
Allow players to be placed out of position on the depth chart. The ability to place someone out of position on the depth chart could be limited to legal position changes, but I would like the ability. And if this option was combined with the options of formation-specific subs, or situational substitution packages, it would also allow things like the wildcat (just put a RB at QB), or a jumbo package where you put a sixth OL at TE on a short-yardage running play, and such. Also, if I want to run 4 wide receivers out and only have 3 healthy I would like the ability to chose which player on my roster fills the 4th spot.
Have the Slot WR position be considered a starting position.
