I don't think you really get carryover these days, just some starting TPE but everyone starts on pretty much a level footing.
Well you can get up to 50 but only if you but you needed 1,200 TPE to get that much carryover. Given when your best players were you're probably looking at like 20 TPE in a best case anyway so not anything revolutionary. But maybe @Beketov will be feeling sentimental.
It's very easy to earn TPE these days tbf
