Here's my thoughts of what to look for:For Buffalo, I think everyone wants to see a tough hardnosed offensive line like they usually have. Peters' departure has been overstated since he missed a bunch of time. A bad offensive line can minimize any good that dis Cecil's son(

) or TO can bring to the team. The Titans DL could destroy them tonight and it probably is premature to write them off. Both teams should have some rust to shake off.The Titans OL is fantastic and I'm sure Bills fans want to see how their DL will stack up.The Titans had 3 of 4 starters in their secondary make the pro bowl last year. This is probably the Bills WRs biggest test this summer.The Bills are expected to start Fred Jackson and mix in some Dominic Rhodes while Lynch is suspended. Jackson needs to keep his edge on Rhodes for FFers to feel comfy about starting him weeks 1-3.The Titans have two former first round picks as a backup QB and generally only keep two on the active roster. That means Kerry and either Vince or Ramsey. (Fisher probably won't cut both if they play great....grain of salt) Ramsey knows the offense better from his time with Heimerdinger in Denver, but (sadly) Vince spent quite some time with McNair discussing Heimerdinger's O and just general NFL QB questions. Part of Vince's whining is that he's put in a ton of work and preparation and is (in his mind) ready to start. Many fans want to see the considerable improvement that should come from that. Ramsey was a once talented prospect many liked and he's fighting for his career really. Which plays better and/or which plays bad, could be a big deal.From what I hear, Kenny Britt won't be a big success this year unless he steps it up. MANY rookie WRs struggle early in camp and "get it" by the time the season starts but generally if they struggle this early they're still a ways off. I think fans want to see whether he struggles or does well to form their own guess as to whether he'll make an impact in 09.Nate Washington and a healthy Justin Gage.Paul Williams was a terrific athlete and an extremely raw prospect. He is in his make or break preseason. He's probably cut but...well let's hope we're surprised how good he's become.I think last year's rook, Lavelle Hawkins, is the Titans slot WR if Britt isn't ready. He moves laterally so well, he's so shifty.Jared Cook out blocking for Chris Johnson. They want to get his speed out in front of Johnson and don't think many teams can match it. They believe CJ was a block away from breaking a run for a TD too many times last year. From there(from there, don't expect catching passes to be his primary job til he blocks well) they want to get Cook matched up on a slower LB catching passes.In just 12-16 hours, many like the idea of Scaife to Philly(although what would the Titans get) and that's not happening unless Cook does well.Titans have a terrific backfield and there's some battles there as they go 5 deep. I wouldn't be surprised if one gets traded this preseason. Jason Jones is expected to bounce along the DL and last year's rook William Hayes is expected to see alot more work this year. Their young DL could spell the end for Jevon Kearse. Kyle Vandenbosch was hurt more often than he played in 2008. Without Haynesworth, they need him to be the star attracting the Ds attention. He can't do that if he's hurt. Jones had 3.5 sacks and 3 forced fumbles in one game last year. I think every IDPer wants to know if he's a superstar or not.
