earthWake - You make good points about the CB's. They were quite a bit different on that unit with Smith and Davis playing together last year. I still do not like changing a defense that was successful though and the offense is going to be brutal. I can't see bringing in a TE who caught 8.7 yards per catch and 8 TD's in his entire college career (playing in a spread offense) having a big enough impact as an NFL rookie on a team with Matt Moore/Ryan Tannehill/David Garrard to move this offense up to a level beyond anemic. If this team finishes 8-8 it will be a tremendous season. I could be wrong though I had my first losing year in the NFL last year and it wasn't just a losing year it was god awful. Agree it will be fun keeping tabs on this team though.
ClubDirt - I couldn't take an Under with Green Bay. This team went 15-1 last season basically without a defense. The dropoff of the Packers defense from 2010 to 2011 was staggering. They were dominant in 2010 and were reason 1A (with Rodgers) as to why they won the Super Bowl. A lot of young guys who were excellent in 2010 (Williams, Shields, Raji, and even Matthews) were terrible last year. Maybe these kids got too much too early and got a little full of themselves as well. Their strategy last year was to watch with stars in their eyes as the offense dazzled and got a lead, then their job was to come in and sit back and look for turnovers. That ultimately did them in as the offense had a bad day in the playoff game and the defense didn't know what to do. I think there are a lot of players on this defense (and consequently the defense as a whole) that are primed for bounce back years. Green Bay also spent it's first 6 draft picks on defensive players. The offense will be a Top 3 unit as long as Rodgers is there. Green Bay won't win 15 games again but I really think they are going to be better than last year (if that makes sense).
My early read agrees with you on the Lions though I don't have a great feel yet. No doubt there is a lot of talent there, but there are also a lot of character/coaching questions as well. The Lions came back from 13 or more points down four times to win last season. There are two ways to look at that: #1. They showed great heart and showcased their talent when they focused and came back, or #2. How many really good teams put themselves in holes like that to begin with? The fact they went 1-5 against playoff teams (The lone win being 8-8 Denver) sends up an alarm bell as well. But if they find a running game, manager to piece together a secondary, and remain disciplined then they could win 10 games but that's a lot of ifs.
Houston can skate to a division title but I have a weird feeling with this team. No doubt they are immensely talented but if seems as if they are putting too much stock into their younger players. They lost Mario Williams, DeMeco Ryans, Eric Winston, and Mike Breisel, the last two being the starting right side of the offensive line. When you trade/cut veterans like that who have been with the team for so long I think you lose a lot of leadership. While there may not be a drop in talent I do believe Houston will feel the emotion loss of those veterans more than anything.
