My view of the Texans:
QB: Good situation, Schaub looked good but the injury bug is a concern. On the good side, Sage is a clone of Schaub and the team doesn't have to change anything when he goes in.
RB: Big need right now. Dayne has been serviceable and better than I expected, but a better RB could have done a lot more on this team.
WR: Going into this year it was one of the biggest weaknesses and areas of need, with no one other than Andre Johnson worth putting on the field. Walter has emerged as a consistent producer, and Andre Davis is providing a deep threat that other teams have to respect on the other side from AJ.
TE: Daniels is a good pass catching TE. I can't attest to how his run blocking is coming along. Dreesen is getting more playing time as well and has looked capable, though I wouldn't mind an upgrade there.
OL: The OL is decent but not great, and has a bad lack of depth. If Charles Spencer can ever return from his major leg injury and live up to the promise he originally showed it would be a huge step forward... but the Texans will be making a mistake if they count on that happening. They need to draft or pick up some additional OL, including a tackle and a guard if possible.
DL: DL is good right now. Mario is providing a good pass rush, and I think Okoye will do better next year as I think he's hit the rookie wall right now. They have a lot of good depth on the D-line, enough that they are always cycling guys in and out and keeping fresh players on the field. Guys like Zgonina, Cochran and ND Kalu have been a big part of the Texans this year.
LB: Morlon Greenwood has really been on fire the last few games. If he keeps this up, he and Ryans could be scary. Coaches have said of Ryans that as a rookie he had the play recognition ability of 10 year veteran starters. It was incomprehensible that Ryans didn't make the pro bowl last year, and the only reason I can see for it was lack of exposure. I would like to see an upgrade at the other outside LB, particularly someone good in pass coverage. It would be interesting to see what special teams standout Zach Diles could do with some playing time.
CB: Ok, big problems here. Dunta Robinson is a very underrated CB probably due to lack of exposure. It was a crime that he didn't make the pro bowl last year. He isn't the best shut down corner though he's very good in coverage, but when you consider the aspect his tackling and blitzing brings he is amongst the best in the league. He's one of the best tacklers in the entire NFL, and definitely the best on the team. However, his injury makes it questionable when he'd be ready to play next year, and I won't expect as much out of him returning from the major injuries he suffered. Faggins shouldn't be more than a nickle in the NFL. Bennett is looking ok but he gets beaten after the catch way too often. Von Hutchins has done ok as well, but really these guys need to improve if they are going to be starters. The Texans should be looking to take a CB in the first next year.
Safety: Along with cornerback, safety was decimated by injuries this year. Starter Glenn Earl and backup Jason Simmons both on IR. Both are decent players but probably below average by NFL starter standards. 3rd stringer safety Von Hutchins may have actually been outplaying both of them, but then he was converted back to CB after the injuries to Dunta and Faggins. Demps and Boulware do not seem like long-term answers to me either. Starter CC Brown is much like Earl... decent, but probably below average by NFL standards.
Special teams: This is an area of the Texans that those who don't follow the team probably aren't as aware of. Special teams has been a big differentiator for the Texans in the games they've won. Jerome Mathis was starting to get close to his old self before being lost for the year. Again. Jacoby Jones looked great at punt returns early in the season and pre-season, but since the injury he hasn't done much. Andre Davis coming on strong at kick returner has been a big deal for the Texans, both in putting points on the board and in giving them a short field to work. This is an area that Houston needs to continue to be good at if they are going to be able to compete in their division, especially against the Colts.
Injuries: Not sure if this stat is correct, but a friend told me this week that Houston led the league in players on IR for 3 of their first 6 years of existence. If that isn't right, as a Texans fan it sure seems believable. I don't know if a stat like that means their training staff isn't doing something right in preparing the players, but they have to keep key players healthy to make a playoff run. The Texans still do not have enough depth at a few areas to be able to put 17 players on IR each season. But the drafting since Kubiak and Rick Smith have come along has been very good, so looking forward to seeing them continue to build up the whole team including the depth.
I think Houston has a positive future ahead of them the way they are going. But they are going to have to build a team capable of competing with the Colts on a regular basis to have sustained success. Otherwise they are in the same situation as Jacksonville, trying to squeak in with a wildcard, and that isn't where you want to be. They have a decent amount of cap room next year, with $20m in dead money coming off the cap from guys from the Casserly era who were cut. That isn't at the top of the list though, so they need to spend it wisely. I'd say their needs in order are:
CB, OL, RB, Safety
