Other than the colossally inept QB play, the overall team speed is severely lacking and is extremely noticeable on the field. That's goes for almost every position. And last year's record was a bit misleading, IMO. The 9 wins last year were to teams with a combined record of 43-101. The only teams they beat either had a rookie QB, a crappy QB (one of which is likely now our starter), or Joe Flacco (who arguably could be lumped into the crappy QB category).

I know Drew Brees is old and looks to have lost it some, but if I'm the Texans, I'm hoping like hell the Saints purge their cap and I'm making a run at him along with drafting a QB high. You have got to fire that draft bullet sooner or later regardless of risk.
