Can somebody tell me where I can find an explanation concerning the option to:

- Change Manually Drafted Prospect Salaries to Real Life Values

I don't know where you can find an explanation, but it's very straightforward. In leagues that use draft-your-own AAA, the players whom you choose as your AAA selections will show up on your roster as having a salary of $200K. Just like SIM-generated AAA prospects do. That's the default option.

If you choose the option highlighted in your post, the players will show their actual salaries.

It does nothing to affect game play in any way - it just lets everyone see the actual salaries of the players who were drafted as AAA.

For example, in the Cooperstown HIstorical Replay League, we replay each season using the exact real life rosters for each team. Each team is allowed to draft as many players into AAA as actually played for their MLB team that season. In 1991, I have the Mets. There are 30 players in WIS who played for the 1991 Mets, so I have drafted 5 of them as AAA: Tom Herr, Charlie O'Brien, Garry Templeton, Todd Hundley, and Sid Fernandez.

All of those guys show up on my Team Manager pages as having a $200K salary.

Their actual salaries are:
Hundley: $967,838
Templeton: $830,567
Herr: $765.020
O'Brien: $1,179,386
Fernandez: $1,1,68,539

That's all it means...do you want to see "200K" or the actual numbers when these players show up on your team?

Note that this setting does not in any way affect TOC seeding either - all teams are placed in a TOC based on the total salary of their final 25-man roster...so regardless of what setting you choose, the real salaries are used for TOC seeding purposes.

Thanks. I was wondering, because when you cut a maually drafyed player you get 200k, if you would get the actual number for WW purposes if that option was selected.
