When it comes to the NFL offseason, the splashy moves draw all of the headlines. Matthew Stafford heading to the Rams had a clear effect on the market; so did Carson Wentz to the Colts, the 49ers' trade for the No. 3 pick, and the retirements of Drew Brees and Philip Rivers.
But what about the moves that might not have grabbed the spotlight? Here are five under-the-radar acquisitions that could have a significant effect on the NFL betting market in 2021.
Joe Thuney to the Chiefs
This one drew plenty of attention when it happened, if only because of how glaring the Chiefs' offensive-line issues were in their Super Bowl loss to the Buccaneers. Still, don't gloss over this move in favor of flashier skill-position signings.
Thuney ranked in the top 12 among guards in PFF grades in each of the last four seasons and has played 500 more snaps at left guard than any player in the league since joining the Patriots in 2016. That consistency and availability is a game-changer for the Chiefs (+500) in their quest for another championship.
John Johnson to the Browns
The Browns seemingly had the makings of a title team last year with an elite offense and burgeoning pass rush. Their biggest weakness was on the back end - Cleveland ranked 12th in points allowed per red-zone trip (4.93) but fell to 23rd in points per drive (2.52), a symptom of poor secondary play and an inability to prevent the deep shot.
Johnson ranked fourth among safeties in coverage grade last year (minimum 100 snaps) and fourth in run defense, too, recording 79 tackles and seven pass breakups with the Rams. He's the type of defensive star who could elevate the Browns (+2000) to legitimate Super Bowl contenders.
