Parker and Grant wrap up their season preview series with a look at the TCU defense and the Horned Frogs' schedule. Topics include:

-- Our new sweet boy on the front line

-- Linebackers: what are they?

-- The secondary should be pretty darn good! And set in stone!

-- No schedule thoughts, just vibes
