I don't get focusing on outside back... At all. It's also not good cap management to pay a backup significant money when you have a guy like Taxi making big money. Plus two other CB's on the back line.
You aren't going to do much better than Murillo and Duncan at RB. I don't think there are any other RB tandems I'd take in the league and I'm not even a big fan of Murillo defensively.
If the issue is that you think MLS has passed Lade by, then fine. Maybe that's the case but having Lade as a backup LB isn't the worst thing in the world.
The team has far bigger issues and LB isn't one. BWP is a huge issue. Kaku is a huge issue. And Armas is a huge issue.
When Lade starts and you know exactly what is going to happen and then it happens...that is a huge problem.
When Murillo is directly involved in giving up a goal a game...that is a huge problem.
Yes, there are a lot of other problems going on right now but when its grade school defending mistakes like staying goal side of your man...
