Coaching Staff:

Offensive and Defensive Cooridinators:
 

There is no definitive way to chose your Off and Def coordinators.  But you should take into account what type of team you have and what your needs are.

For Lowly ranked teams with lots of young players who you want to develop to close to there potential you should look for coordinators with the following:

I don't have the exact numbers for how mnay time blocks you will get from a coach with COneniality factor, but I will try to look into this over the weekend.
It was discovered earlier that Congeniality actually affects how many coaching blocks you can give away. If you have coaches with low congeniality, you will have fewer blocks, I believe in the 30-35 range. However, coaches with high ratings and you have close to 55-60 blocks.

Coaching Blocks Available based on Coaching Congenieality

excellent 35-36
terrific 33-34
verygood 31-32
prettygood 28-30
good 25-27
decent 23-25
fair 20-22
poor 18-19
lousy 16-17
terrible 14-15
 

The last three general categories are Low Injury Rate, Playcalling, and Rehabilitation.  All 3 are very important but you need to have some one that will cater to your strenghs.  If you have a deep team (Penn State, FSU etc.) you can probably not worry about Injury rate of Rehab as much.  As you will have adequate backups on your bench.

If you don't have much depth to your bench your best bet is to get the best balance out of those 3 for both offense and defense.  The reason is there is no reason to have good players if your coach is going to call bad plays for them all the time.  Also you don't want to be calling great plays in every situation if your star RB, QB, LB is injured and the backup won't due that good of a job.
 

On Offense
 
 

If you are more of a runnnig team you might want a Coordinator with a Strong RB, OL and maybe QB developement.  This is probably a better way to go with a younger unproven team as you should eat up more game time.

If you are going for a pass based offense a strong OL, QB, and WR developement is key.

I tend to put very little emphasis on Kicker developement early on in careers with poor teams.  One reason is that a kicker/punter is unlikely to win me too many games.  While strong positional players are more likely to put my team in positions to win.
 
 

For Defense:

For defense I think you need to know what type of teams you will be playing.  There is no easy way to determine if most teams are pass oriented or run oriented at the get go.  But after a season you can look at other teams stats and see what there tendancies are.  If you are in a pass oriented confrence you should probably recruit better CBs and Safties but also make sure you Secondary developement is better so you get the most out of thos players.

For teams with a higly run based confrence your LBs and DLs will be more important.  Now depending on what kind of defense you are playing with you can try to match a coordinator that will help out with this.  I usually only use 3-4 and 4-3 but it should work the same for all defenses.

If you are going to have more DL (DE and DT) go with a 4-3 and get a Def coordinator with better DL developement, and Vice Versa for LB development in a 3-4.
 

Scouts:

The most important Scout in the game is the one from your home region.  He not only evaluates your team he will also evaluate all the players surrounding your school.  This will help in having a good feel for what players you are recruiting as well as the players already on your team.

The only other thing to look for in scouts is what type of offense you run.  If you do a run and shoot and don't utilize running plays much a Scout that is bad at evaluating RBs won't hurt you as much.  But if you do a Run and Shoot and a scout is poor at evaluating QB and WR you should probably stay away from him.
