Some side notes start putting in players personality like team leader, distraction, or mentor. Have the progression screen progress players more realistically. Like let players get big bumps in overall for the players who have a real break out year.
It would also be awesome to do multiple team trades or even trade for cash. Even do trades where you can pay a portion of the player you are trading away salary so you can do a trade with a team that has limited money.
Just a few ideas. I must also state that I love all the continued progression for MLB The Show and what you all do to make such an amazing game. Sorry this was longer than I thought, but I have a ton of ideas.
