If one of the top 4 QBs falls to Houston in the first round, they need to take him. No questions asked.
Now that they've assembled a hella talented team, Schaub is starting to show his true colors as a QB who's only just good enough to get his team beat. They need to put together a Plan B... at the very least maybe it will light a fire under Schaub's ass. This may be one of the last times that they'll be in a position to draft a pretty good first round quality QB without trading up.
And yeah, they need WRs like hell, and this draft will have some good ones fall to around their pick, but the future comes first.
Of course, that will be exactly what they WON'T do. But that's okay. As long as the Cincinnati Bengals keep making the playoffs, they'll get their one playoff win every year.
