This is weak. Both TEs aren't helping Brown on any play and it's rare that one of them is doing more than chip. That's normal TE behavior and it doesn't preclude them from running routes more elaborate than standing still by the sideline 3 yards up field.
Just spitballing, if you're having trouble containing the left DE and you are often using a TE to help, a TE screen is a viable option that takes advantage of your players' athletic ability and also serves to slow down future pass rush. We don't do that.
