Week 1 takeaways First impressions of Alabama, Ohio State, Michigan - ESPN

By now, you know Deion Sanders has taken over the college football universe after his unique transfer-heavy Colorado roster upset TCU in his first game as an FBS coach.

Alabama quarterback Jalen Milroe brought out the whole arsenal against Middle Tennessee, showing off his scrambling ability as well as his strong arm. His first touchdown, when he scooped up an errant snap and ran 21 yards into the end zone, was special. You can't teach that type of playmaking ability.
