yea, you could sell your DL for someone with a higher q.
he is young with sa, so he could bring you some good money from the market.
Also, you could buy some back up players like a DMC-DC (if I can see correct - it's a little mess) you don't have a second one.
You could buy and use a 3* retired veteran you know, a free agent - but I don't know if you 're playing anywhere else beside the league.
It's good if you ask advice, to give the whole picture.
Three main statements -
What I want
What I can get
How I can support it
