On a night in which Titans coach Mike Munchak was looking for clarity, there was confusion. Locker played like a young quarterback. It happens. He was inaccurate and made poor decisions. His final box score was about as ugly as it gets.
In Arizona, Raiders defensive tackle Tommy Kelly reportedly yelled "That boy's scared" about Kevin Kolb while running off the field. We suspect it will be the last time Kolb is with the starting unit for a while.
Preseason performance doesn't often carry over in the regular season, but it does decide jobs. Locker and Tannehill failed to provide final answers Friday night. Kolb did, but not in the way he wanted.
Here were our other takeaways from Friday's six-game slate.
» Early signs indicate Buccaneers running back LeGarrette Blount's groin injury is not too serious. But we won't really know anything until further tests are done. Rookie Doug Martin looked like he could handle things as the lead back if necessary. We love his vision and change of direction.
» Detroit's versatile return man/running back Stefan Logan was in a boot after the game. X-rays were negative on his ankle.
» Jonathan Stewart left the game with a calf injury, but he tweeted after the game it wasn't serious. We'll take his word for it; Stewart was seen dancing on the sidelines in the fourth quarter.
» Cam Newton looks ready for the regular season. Three drives, only three incompletions, and 17 points scored.
» Vince Young probably did enough to win the backup quarterback job in Buffalo. He looked solid, and Tyler Thigpen struggled again.
» It's only the preseason, but Blaine Gabbert looked a lot more comfortable Friday night. He got the ball out of his hands quickly, going 13-of-16 for 112 yards and two scores. Best part: a few of those passes were delivered while getting hit. Maybe he'll quiet those critics after all.
» After Kevin Kolb struggled, John Skelton went 3-of-3 with a touchdown pass. That's it. It's very telling Ken Whisenhunt then pulled Skelton. It's almost as if Whisenhunt didn't want Skelton to potentially ruin the narrative with a bad throw. We'd guess Skelton is named the starter this week.
» Raiders receiver Jacoby Ford left with an ankle injury. Darrius Heyward-Bey dropped a sure touchdown pass. Denarius Moore can't get healthy. The only Raiders wideout exceeding expectations: Undrafted revelation Rod Streater.
