or even better than all the above
START UNEMPLOYED
This makes for a really fun game, I agree.
Another option is, if you really do need to start with a big team, buy young players and sell/release lots of older players. (For instance, if I was managing chelsea, right from the beginning, I would sell/mutually terminate Drogba's, Anelka's, etc. contracts and replace them with players like Erick Torres or Carlos Fierro (both of which have great potential and play for Chivas). There is few more satisfying FM experiences than taking a nobody like Erick Torres who has loads of potential, introducing him to the EPL and watching him light it up. Just buy a ton of good, young players and make a dynasty, much like Sir Alex did with 'Fergie's Fledglings'.
My advice would be to stick with a save for at least 3 seasons. Once you are in your 3rd/4th season, it gets REALLY fun. You, more than ever, begin to feel like a real coach, because you have to scout guys you have never heard of or seen before. Regens make the game amazing fun. Some guys have amazing potential.
At the beginning of games, even if you find or buy wonderkids, it feels like you personally will never find the next Messi or Ronaldo because in real life if the player had that much potential, everyone would practically know about him already (like Eden Hazard). But with regens, you truly can find the next Lionel Messi.
