A source tells Mike Giardi some Patriots "don't feel appreciated," and Bill Belichick is making "planet players" (such as Tom Brady and Rob Gronkowski) miserable.

Someone who "knows" is watching our show tonight. Source says Bill is making "planet players" miserable and yes, a lot of this ties back to the Alex Guerrero stuff. The players - like Brady and Gronk - "don't feel appreciated for the sacrifice they make."

Source still believes Gronk will play and will be armed with a raise when all is said and done. https://t.co/BLdmQY8omJ

Definition of planet players...Brady and Gronk

The news doesn't come as a total surprise. It's no secret there was tension within the Patriots organization throughout the 2017 season. 

Giving Gronk a raise might solve some issues there, but it remains to be seen whether things can be fixed for other players who don't feel appreciated.

Will Patriots owner Robert Kraft soon match Red Sox principal owner John Henry by investing in a European soccer team of his own?

According to Spanish media reports, Kraft is close to buying a stake in the Spanish soccer club Sevilla of LaLiga. Spanish radio network COPE reports that the sale of a 40 percent share of the team to a "U.S investment group" could come this week.

More from the website SoccerEx:

Kraft, who is chairman and chief executive of the Kraft Group, is apparently leading this consortium, possibly through an investment company called 'Sevillistas Unidos 2020’.

The Patriots were valued at $3.7 billion - the second-most valuable NFL franchise behind the Dallas Cowboys - in the latest Forbes ranking of world sports franchises. European soccer teams hold three of the top five spots.

In 2005, Kraft considered purchasing English Premier League team Liverpool FC, which was purchased by Henry's group in 2010.

The Kraft group also own the New England Revolution of MLS and the Boston esports franchise in the Overwatch League.

After 11 seasons, Revis Island is officially closed.

Former Patriot cornerback Darrelle Revis announced his retirement from the NFL via Instagram on Wednesday, ending his career after 11 years with four teams, including two stints totaling eight seasons with the New York Jets.

A post shared by Darrelle Revis (@darrellerevis) on Jul 18, 2018 at 7:45am PDT

"It has truly been an honor to showcase one of my greatest gifts to the world,” Revis wrote. “Today I am closing a chapter of my life that I once dreamed as a kid and I am officially retiring from the National Football League."

Revis, who turned 33 July 14, was a key member of New England’s Super Bowl XLIX winning team that beat the Seattle Seahawks in 2015. Last season, he appeared in six games for the Kansas City Chiefs, including the playoffs, before being released in February.

After being released by the Tampa Bay Buccaneers in March 2014, Revis signed a one-year deal worth $12 million to play in New England and earned first-team All-Pro honors in his only season in Foxboro. He then signed a five-year, $70 million contract to return to the Jets in March 2015.

Here's the Jets' statement on Revis' retirement:

While he won his lone championship in a Patriots uniform, Revis found most of his individual success playing for the Jets, who drafted the corner 14th overall out of the University of Pittsburgh in 2007.

A seven-time Pro Bowl and four-time first-team All-Pro selection, Revis’ ability to shut down opponents top receivers one-on-one earned him the “Revis Island” moniker.

Widely considered one of the greatest cornerbacks in NFL history, Revis finished his career with 29 interceptions, tied for 225th all-time, a testament to how much quarterbacks avoided throwing near him.
