Everyone knows our attempts at resolving these two positions. Are great left tackles and "shutdown" corners a dying breed? The Texans efforts to fill these positions are well chronicled with more misses than hits at getting even adequate players. Yeah, I'm hopeful on Charles Spencer too; but do we have more than even odds he will play this season, let alone become a solid starter? Shifts in defense and offensive blocking schemes have been created to hide weaknesses; but an 'uh oh' by either can cost you points or worse your starting QB.
