Your team doesn't look to bad, but here's my thoughts:
Tannehill is a guy I'd drop. Find out what week Stafford is on a bye & see what match ups free agent QB's have that week. I've got Tom Brady & picked Joe Flacco as my backup because he's playing the Browns on the Patriots bye.
I don't know if I'd keep 3 TE's. Tamme & Gonzalez are the two guys I'd keep, then pick up a backup defense.
