I've gone through an update of the
2009 cap page (yes, finally). I think I'm within a half million or so, who knows, maybe less, as the team closed out with around $4 million in leftover cap space from what I can tell.
So, moving onto 2010... I don't expect a CBA extension before the dawn of the new league year, so saying the Texans have $x million of space available is probably meaningless.
And it's kinda too bad really, since 2010 might have been the team's best ever in terms of cap readiness for the new season, though granted they have quite a few young players owed new long-term deals.
