1. You hire replacement coaches, trainers and Gms in the offseason, after the regular season is over. Teams that don't make the playoffs get first choice at hiring coaches.
2. I think it's the small, middle, and large school scouting skill. You start with the rookie's strengths, weaknesses, and player comparison unlocked. You get all 3, you get them for the entire draft class.
3. Mock draft gives you an idea, and also the player's overall. You can plan where to draft your players from that.Teams will usually draft a player based on what their overall is when you scout the player to 79%. For example, Patrick Boma with a overall of 68 can expect to go in the 3rd or 4th round.
4. Receiving HB if you plan on having your back catch a lot of passes, Balanced HB otherwise. Balanced philosophy will give you the best all-around back. The Balanced philosphy will usually give you a well-rounded player, so I use that unless I need a different philosophy for my scheme.
5. Most player start with high physical development scores, so developing intangible ratings are very important. You also want a player with a good athletic score.
6. Your co-ordinators and assistant coaches can focus on regular skills, I'd go with special skills the first year. The Seminars, Playbook Training, Charm, Charisma, Leadership, and Ambition(hope you got that starting out). Get Performance to level 3, Team Chemistry and Strategy to level 3 if you play the games, and Playcalling to level 3 if you- supersim the games. I really don't think you need your HC to focus on player devolopment the first year.Performance affects how you players play on the field,so I'd max it out as soon as possible.
