Study: Effect of coaches

[CBeisbol]

People were asking about coaches, so I decided to take a quick look

OOTP XX - Standard Game

All league settings set to discourage randomness (no trades, no development, no injuries, personalities and morale off, etc)

Phillies as the test team

Altered the ratings of the pitching coach and hitting coach
Base: all ratings = 100
Good: all ratings = 150
Bad: all ratings = 50

16200 (10 seasons) game sims for each test


RESULTS:
No obvious effect
With the pitching coach, the team won more games with the good coach and the bad coach. They gave up less runs with the good coach and the bad coach. ERA was .01 better with the good coach, but equal with the bad coach. Walks were the same with the good coach, but better with the bad coach. Fewer strike outs with the good coach, and even fewer with the bad coach.

With the batting coach, the teams also won more games with both the good coach and the bad coach. But the team scored almost 10 more runs with the good coach, while scoring 3 less with the bad coach. Batting average was .001 better with both coaches. Walks were slightly higher (.01) with the good coach and slightly lower (.01) with the bad coach. Strikeouts were down with the good coach, but down more with the bad coach.



EDIT
As pointed out in the following posts, but not made clear in this post, this study gives evidence that coaches have no direct impact on performance

Coaches would still be expected to have an indirect impact on performance through development and morale.

Awesome, thanks for the information!

Based on the looks of this, coaches don't matter at all, basically -- the batting coach run difference comes out to roughly 0.1 wins/season, the pitching coach even less. I guess the other factor is development, but that's going to be really hard to measure any difference in, given how random it is in the first place.

If there’s no development and no personality/morale, I would expect there to be no effect of coaches, yes. All coaches really do AFAIK is manage personalities, influence development, and occasionally help players break out of slumps.

So, as soon as contracts come up I guess I'll be replacing my coaches with the cheapest I can find. That stinks so much...As a newb to the ootp world, it really depresses knowing that people have been asking for an overhaul of the coaching system in ootp and for years it's been ignored completely. Thanks for the info CBeisbol...

Again, what did you expect? Coaches are there to influence development and manage personalities. When you eliminate that from the game, why is it so weird that they no longer seem to have much of an effect?

I would not recommend that

As Syd said, there's still development and personalities/morale

This only suggests that they have little to no effect on performance

Ahhh... I didn't know Batting & Pitching coaches had an effect on personalities & morale.

This study confirms everything that is stated about coaches in the manual... what needs to be studied is how the Development engine responds with different coach ratings, player personality ratings, bla, bla, bla...

OOTP has already created a matrix for this... Anyone feel like recreating it...NOT...

It is good to see studies like this that prove the manual correct...

Thanx for the work...

hello everyone,
Coaches impact their players by teaching life skills in hopes of developing positive relationships. Establishing a positive athlete-coach relationship is critical to achieving effective communication. shareit free movies

Reminder

The study only shows that coaches have little to now direct impact on performance, it makes no comment on morale or development - which would be expected to have an indirect impact on performance.
