Bill O'Brien delighted with DeAndre Hopkins improvement

Houston Texans head coach Bill O'Brien has revealed that DeAndre Hopkins has made significant progress in his development during the off-season.

The wide receiver had an impressive rookie year despite the Texans struggles last season, and O'Brien feels that the hard work Hopkins is putting in during practice is yielding results.

"He's one of the guys out there that I think is much improved from April 7, when we started, to where we are now," O'Brien told reporters.

"He just has to keep it going. He's a very hard worker. It's very important to him. He's a guy that really, in our opinion, gets better and better everyday. So just got to keep it going."

Hopkins recorded 52 receptions for 802 yards and two touchdowns in the 2013 season.
