Thomas/Bucs def for matt Ryan/Allen Robinson

I’m in a keeper league that someone dropped out of and already found myself with a rough start.
I was looking to upgrade my quaterback and found this deal
Would it be a bad deal to trade Thomas and Bucs def for Matt Ryan and Allen Robinson?

This is my first year with the footclan and thanks for your advice!!!

What are the keeper rules?

Who are the top FA QBs?

If you can hold on Wentz, plug and play some QBs, Id rather have MT later in the year when it matters

Keep one player in the same spot he was drafted, if keep again the next year after its first round pick
