Agree 100% with MikeT's analysis that a global spreadsheet would be insane. I love a spreadsheet and data bases and spending too much time on these games as much as anyone, but the time needed to catalog every player on every team in every one of my worlds — and then to dig through that data — is indeed insane. Between stats, draft position or IFA bonus, age, makeup, past contracts, you can make an educated guess about players' outlook. At least close enough to mirror the educated guess 5 seconds of 4th-grade math will give you under the current system. Anyone willing to put an insane amount of effort in will always be able to find tiny advantages; this might be one more but nowhere near enough people will do it for it to matter.
