Tuesday is the last day that teams can make trades, as the NFL trade deadline.is at 4 p.m. ET. Yesterday already saw two major trades take place as the Houston Texans moved on from Dune Brown, while the New England Patriots parted with Tom Brady's supposed heir apparent in Jimmy Garoppolo. An even more stunning move took place today, as the Miami Dolphins parted with Jay Ajayi.

Duane Brown

On Monday, the Houston Texans traded left tackle Duane Brown to the Seattle Seahawks. In return, they received a 2018 fifth-round pick, a 2019 second-round pick and cornerback Jeremy Lane.

This move helps the Seahawks as their offensive line, which was putrid going into the season, has suffered from injuries. They were willing to move a lot to get the 32-year-old, who is a three-time Pro Bowler.

Houston has now moved on from their longest-tenured player, who had just come back to the team after his long contract holdout. In return, they get a key draft pick in 2019 and Lane, who was the Seahawks nickel corner last season before losing his job this year to rookie Shaquill Griffin.

Jimmy Garoppolo

Yesterday also saw the New England Patriots trade backup quarterback Jimmy Garoppolo to the San Francisco 49ers in exchange for their 2018 second-round pick.

Following an offseason of speculation, they finally moved the coveted backup now before he is set to become a free agent. The winless 49ers were not thrilled with free-agent acquisition Brian Hoyer or third-round pick CJ Beathard, so they took a risk now to get their quarterback of the future instead of doing so in the draft.

The trade has now left the Patriots, without a backup to Tom Brady, as they traded third-string quarterback Jacoby Brissett in September. However, the 49ers released the aforementioned Hoyer following the trade and he has past experience with the team and their offensive system.

Jay Ajayi

On Tuesday morning the Miami Dolphins made a surprising move, trading starting running back Jay Ajayi to the Philadelphia Eagles in exchange for a 2018 fourth-round pick.

For the Eagles, this move is a no-brainer, as Ajayi is only 24 years old and signed through 2018 on a cheap rookie deal after being drafted in the fifth-round in 2015. Last season he rushed for 1,278 yards and managed eight touchdowns while being selected to the Pro Bowl.

For the Dolphins head coach Adam Gase has been publicly frustrated with Ajayi this season for trying too hard to seek out big plays. Ajayi has struggled this season, recording 465 yards and no touchdowns in seven games. While some of this is on the offensive line, his yards per carry have gone from 4.9 last year to 3.4 this season. ESPN's Jeff Darlington also reported that the team is concerned about his long-term health, as all of this factored into the team's decision.

Rashard Robinson

The San Francisco 49ers traded second-year cornerback Rashard Robinson to the New York Jets for a 2018 fifth-round pick.

The 22-year old Robinson was drafted in the fourth-round out of LSU and has started 13 games for the team, including seven this season. He has 27 total tackles, one interception, one forced fumble and one fumble recovery this season.

Last week, Robinson was demoted from the starting lineup, as the 49ers were not happy with his process this season. In making the trade, the Jets front office believes that they are acquiring a young player who has room to grow into a key piece of their defense.

Kelvin Benjamin

The Carolina Panthers traded top wide receiver Kelvin Benjamin to the Buffalo Bills in exchange for 2018 third and seventh-round picks.

This moves comes as the Panthers offense has been up and down this season, so it seems like an odd time to trade their top receiver, especially after they picked up his fifth-year option in May. However, Benjamin came into camp overweight this offseason and maybe the team did not want to pay him so they got what they could for him.

Buffalo trading for Benjamin should help their passing offense, which has been bad after losing Robert Woods in free agency and trading Sammy Watkins. Free agent acquisition Andre Holmes and second-round pick Zay Jones have not cut it, especially after starting tight end Charles Clay suffered a torn meniscus earlier this month.
