The Chiefs placed the franchise tag on Ford last week, but they did so with the intention of looking for a trade partner for the 27-year-old linebacker.
Ford posted a career-high 13 sacks last season and led the National Football League with seven forced fumbles.
Then again, a fresh start being a great opportunity for Ford also means the Rams now have one more key player to worry about during the 2019 season and beyond since the NFC champions are fortunate enough to play the 49ers twice each season.
From that perspective, adding Ford for a 2020 second-round pick, which will likely be further down the board than the No. 36 selection in next month's draft, makes this a good deal for San Francisco. While Ford can play both, he excels as a pass-rushing outside linebacker which made the Chiefs explore a deal.
If the Arizona Cardinals, who own the No. 1 pick in the draft, select Ohio State EDGE Nick Bosa, that leaves the Niners with two logical options - to try to trade down in the draft, or to draft Alabama defensive tackle Quinnen Williams or Kentucky edge rusher Josh Allen.
After an excellent 2018 season with 13 sacks and 55 tackles, Ford has earned a payday.
He only had 2.0 sacks in six games in 2016, but had 10 the year before that. "He's had some production and if he is here with us, I'll be excited to have him and be excited to work with him".
The 49ers ranked No. 22 in sacks this past season after getting to opposing quarterbacks just 37 times. There were rumblings in KC about Ford being a bust after being taken with the 23rd overall pick in the 2014 draft out of Auburn.
MMQB first reported on the trade agreement.
