As NFL Media Insider Ian Rapoport advises, don't rule it out.
Rapoport said Sunday on NFL Network's "Total Access" that, after talking to sources familiar with Texans general manager Rick Smith's thinking, he no longer believes it's a certainty that Houston will pick Clowney if it keeps the No. 1 overall selection.
Now, it's still possible the Texans won't be picking first -- they've made it clear that trading down is something they're entertaining. Owner Bob McNair and Smith are at least on the same page on that front. However, it doesn't appear that the owner and general manager are in lockstep when it comes to ranking Clowney and Mack. McNair said Friday that Clowney is "obviously the best player in the draft," but Rapoport's report indicates Smith might feel that the answer to who's No. 1 isn't so obvious.
Or maybe the Texans are muddying the waters as much as they possibly can as they put on a full-court press to find out what the highest bid would be for pick No. 1.
Rapoport said Texas A&M's Johnny Manziel is another name to consider at No. 1 -- although he's not considered a perfect fit for head coach Bill O'Brien's offense -- and also mentioned that the Texans' talks with teams that might be interested in acquiring the No. 1 overall pick have yet to get serious.
