New player models would be great but at this point, just sliding the scales so everyone looked 20-30 pounds lighter would make a huge difference. Guys like Kawasaki should look like a stick but look normal in game. Guys like Altuve should look athletic but right now look overweight. guys like Donaldson and Tulo shouldn't look so jacked up. Even big guys like Schwarber would look better by being less round. Ex. A 6', 220 pounds should look like what someone 6', 200 pounds looks like now, or somewhere around there and should be applied across the board. No idea if there would be repercussions with the animations or not of course.
