Here are three things to watch when they kick off tonight at 9pm EST.
1) Is the Titans' offensive line really better? It's been a thorn in the side of head coach Mike Munchak since he took over in 2011 and they've tried to address it this offseason by signing former Buffalo Bills guard Andy Levitre and drafting Alabama's Chance Warmack with the No. 10 overall pick in the 2013 NFL draft. Levitre is dealing with a knee issue and might not play much, if at all. Warmack was the last of the 2013 NFL first round draft picks to sign and is still catching up. The team needs them healthy and ready to go if they have a hope of improving the offense.
2) If Griffin is back Week1, who is going to catch balls for him besides Pierre Garcon? We should start seeing some answers to that tonight. It's not an incredibly exciting group. Josh Morgan has never lived up to his promise, nor has Leonard Hankerson. Santana Moss' production fell off a cliff last season, while tight end Fred Davis has the talent but lacks the focus. This group will be under a spotlight not just tonight but the rest of the preseason.
3) We know Chris Johnson can run the ball, but is Shonn Greene worth the three-year, $10 million deal they gave him? Despite a pair of 1,000 yard seasons for the New York Jets, he's been a lackluster and uninspiring runner. Will he fit on this team as a change-of-pace back? Or will guys like Jackie Battle or Jalen Parmale prove a better—and cheaper—option?
