Q: How are players reacting to new head coach Bill O'Brien's style?

A: It's a more confrontational style than that of former coach Gary Kubiak. Handled the wrong way, a coach's abrasiveness can cause players to bristle, but that hasn't been the case in Houston. Rather, Texans players have said they like O'Brien's style because while demanding, it's fair. In one breath, O'Brien will scream at someone who messed up and in another pull someone aside to explain how better to accomplish what he needs to do.

When O'Brien came to Houston, the expectation was that, like some other former New England assistants, he would be a Bill Belichick clone -- uncompromising, paranoid, meticulous and determined not to offer any glimpse of personality about him or his team. That hasn't been the case in front of cameras or behind the scenes with O'Brien. He laughs and tells sarcastic jokes at news conferences. He offers colorful anecdotes at times. He has a temper but also a keen understanding of how to get along with people. Behind the scenes, he makes players feel like their opinions matter to him. He meets with groups to hear what they have to say.

"To be honest with you, from the time we've arrived here, it's been really a neat experience to get to know these players and see what they're all about," O'Brien said.

Getting to know a player can be about getting to know him both on and off the field, to know his strengths and fit the scheme to those strengths. Players appreciate that, and they'll appreciate O'Brien's style as long as it works.

Q: Has the Colts' offensive line improved enough to allow Andrew Luck to take better advantage of his weapons at receiver and tight end?

A: The Colts can be one of the highest-scoring teams in the league if -- a big "if" at this point -- the offensive line can do its job of blocking for the running backs and protecting Luck, who has been sacked 73 times in two seasons.

The Colts departed minicamp with questions remaining about the interior of the offensive line, which was the weakest link of the group last season.

Working with the first team at one guard spot was second-round pick Jack Mewhort, who played tackle during his final season at Ohio State. The starting center is Khaled Holmes, who got on the field for a total of 12 snaps as a rookie in 2013. The other guard spot was manned by Hugh Thornton, who struggled while starting 14 games as a rookie because of a season-ending injury to Donald Thomas in Week 2.

That's a scary scenario to think about if you're Luck, offensive coordinator Pep Hamilton or head coach Chuck Pagano.

The Colts shied away from pursing a starting-caliber center in the offseason. They signed Phil Costa, only to have him abruptly retire.

Thomas is expected to be ready for training camp and will join Lance Louis in competing with Mewhort for a starting guard spot.

The easy way to look at things would be to say the line might not be better, but it can't be worse than last season's group. Thornton has a year of experience, and Thomas and Louis both have started at different points in their careers. Pagano and general manager Ryan Grigson continue to defend their decision to go with Holmes. Grigson believes Holmes could have played last year if he didn't fall behind his teammates after missing most of training camp with an ankle injury.

Still, there's no reason -- not yet, at least -- to think Luck won't be sacked a lot again this season.

Q: Jaguars GM David Caldwell and coach Gus Bradley have said rookie quarterback Blake Bortles isn't going to play this season. Is that the correct decision?

A: When a team drafts a player with the third overall pick, there's an expectation that the team is getting someone who can make an immediate impact -- not someone who might not even contribute for a year. But that was the book on Bortles throughout the draft process. Most draft experts agreed he was a player who needed more time to develop to become a quality NFL starter. His lower-body mechanics need to be improved, and he needs to become a full-body thrower, instead of relying on just his arm.
