Coach Madden Question

Gotta wait for season 5, but since you have yet to make, if you can be patient you can make him in series 1 and sell him off to eventually recoup what you spent

I bought Coach Madden a month ago and have added Madden Passing (tier 2), Pass D (tier 1) and Physical 

My question is can you keep turning in series 4 trophies for more more Madden Schemes or to you have to wait til series 5 or something?

I see a bunch of additional tiers including another Physical + Scheme one a few upgrades away from where I am.
