I wish we could see more of a stat grind for the original TA cards... In example, I have been using Gleyber Torres from the moment I unlocked him and have very good numbers with him and probably would be close to prestige him if it were an option.
Overall, TA is a way to show off your team... Prestige is a way to upgrade your favorite players and show them off. Why not combine them and offer stat grinds for at least the original TA cards? It would add to the already existing longevity of TA this year.
With Inside Edge absent this year, this would be a nice way to increase stats of today's stars.
