Q1--Is BYU's defense all that holding a very high-powered SMU offense to 15 points despite BYU's TOs and multiple 3-and-outs?

Q2--Is TCU really so bad this year that they give up 66 to SMU who is in their 1st year in a P4 conference?

Q3--How good is SMU really, and what does BYU's victory over them on the road portend for the rest of the Cougar's season?
