>>Lovie Smith Out In Tampa

Out of nowhere on Wednesday night the Buccaneers dismissed second-year head coach Lovie Smith, the team announced.

Tampa Bay improved from a two-win season (and the No. 1 overall pick) to 6-10 in 2015 and showed serious signs of improvement with first-round pick Jameis Winston under center.

However the Glazer family -- through a statement from Buccaneers co-chairman Joel Glazer -- decided it was time to move on from Smith.

"After careful consideration, we informed Lovie that we have decided to make a change. I want to thank Lovie for his hard work and dedication to the Buccaneers during his time here," Glazer said in a statement.

The move came out of nowhere, making it perhaps the most difficult offseason coaching move to parse.

>>Sean Payton Returns To New Orleans

In another unexpected development during an offseason that now seems like it's going to feature a bunch of those, Sean Payton is staying on as head coach of the New Orleans Saints.

Rumors had been swirling that Payton would leave New Orleans throughout much of the season, and they had picked up steam up in recent days as teams like the Giants and 49ers parted with their own head coaches (Tom Coughlin and Jim Tomsula, respectively) earlier this week. Reports earlier in the week indicated that the Saints were seeking at least a second-round pick to pry Payton away from them, and Giants owner John Mara did not deny that his team would be willing to deal picks for a coach.

Instead, as reported by CBS Sports NFL Insider Jason La Canfora and others, the Saints will not be making Payton available to other teams, and the NFL's current fourth-longest tenured head coach is sticking around for at least one more year.

Payton has been with the Saints since 2006, the same offseason during which the team signed Drew Brees. Since then, the team has routinely ranked near the top of the league in many offensive categories on a yearly basis. The Saints are 87-57 under Payton's stewardship, which does not include a year during which Payton was suspended and the team went 7-9. That 94-66 total record is the sixth-best mark in the NFL since 2006, and the 87-57 mark gives Payton's version of the Saints the fifth-best winning percentage in the league during that time.

>>Calvin Johnson Mulling Retirement

Detroit Lions wide receiver Calvin Johnson is 30 years old. He's played nine seasons in the NFL. And he has recently told some former teammates that he is considering retirement, according to the Detroit Free Press.

"There has been some conversations about it, not asking me how it is," said one former teammate who asked to remain anonymous, per the Free Press.

According to Terry Foster of CBS Detroit, Megatron has been picking the brains of former teammates about what life is like after football, hinting that the Lions star could follow in the footsteps of Hall of Famer Barry Sanders.

Johnson has been one of the best, if not the best, players at his position since he entered the NFL out of Georgia Tech back in 2007. In that time, Johnson ranks seventh in the NFL in catches and first in both receiving yards and receiving touchdowns. His 731 catches are the sixth-most ever for a player in their first nine seasons, while his 11,619 yards rank third, and his 83 touchdown grabs rank fifth.
