The Dolphins made a number of moves this offseason, and Barry Jackson of the Miami Herald writes that the team was focused on improving the locker-room culture. The front office deliberately pursued team-first players who would “buy in, be diligent about studying and preparation, and do things the way the staff wanted.”

While the organization may have been focused on shifting the culture, quarterback Ryan Tannehill didn’t believe there was a culture issue in the first place.

“I don’t think we had a bad culture,” he said. “I think the guys that we brought in have already bought in and now we’re fully aligned and we can just drive forward. I think that’s a big factor in the performance of teams is everyone being on the same page.”

On the flip side, Jackson writes that safety Reshad Jones did admit that he’s already seen improvements to the team’s mindset.

Let’s take a look at some more notes from around the AFC…

• Jackson notes that Dolphins undrafted rookie cornerback Jalen Davis received a $20K signing bonus on top of his $25K in guaranteed money. The writer wonders if the defensive back could end up sticking around, especially since he earned the most money among the team’s undrafted free agents. Linebacker Mike McCray received $12K in guaranteed money and and a $1oK signing bonus.
• The Ravens added quarterback Robert Griffin III earlier this offseason, and they subsequently drafted signal-caller Lamar Jackson. While the rookie will surely provide the 28-year-old with some competition for backup reps, Griffin told Mike Jones of USA Today that the draft selection wasn’t a slight at himself or Joe Flacco. “When they drafted Lamar, I didn’t look at it as a shot at me or a shot at Joe,” Griffin said. “It was ‘OK, Lamar is coming in here, and it’s our job to help him learn the offense and help him compete.’ So, for me, my job is to show them that I’m an asset to the team and not a detriment. … One (reporter) asked me if I was trying to showcase for other teams. No, my focus is, ‘I’m a Baltimore Raven. I’m showcasing to them that this is where I’m supposed to be.’ ”
• The Browns made several personnel changes today. ESPN Cleveland’s Tony Grossi writes that personnel executives Chisom Opara and Bobby Vega (as well as area scout Patrick Moore) have left the organization. Grossi also notes that general manager John Dorsey could end up pursuing former NFL linebacker and current radio host Matt Wilhelm for a front-office gig.
• We heard earlier today that the Patriots and tight end Rob Gronkowski were zeroing in on a new contract.
