If you buy a good young 18 yr old CB, and plan to keep him a few seasons, it’s worth training DL, or DR as that will make speed a highlighted attribute and ensure his speed stats don’t get warped down to 30% after a few seasons while his major stats are 150%+.

I just bought a 99% 18yr old DMC and have trained MC today so that he now only has 2, greyed stats. Crossing and finishing, which he doesn’t really need as my long term DMC.
