Hey man, I don't know if you already found another roster with Roberson in it that you can enjoy, but if you don't take the time to read my latest (long) post...
I can try to add Robertson later, but as of now there are only (I believe) 112 CAP slots available and I'd prefer to use those for the top draft picks.
If it becomes obvious he'll make the team (and preferably have a role/make an impact) I'll be happy to try and add him.
