The seemingly ever-constant commotion of NFL transactions is in a rare hiatus now that the league is in the midst of its dead period before training camps open up later this month. The main waves of free agency along with the NFL Draft have come and gone, so we have a good sense of what rosters are set to look like once Week 1 rolls around. 

Just like every offseason, this year's game of musical chairs didn't disappoint as a number of the game's biggest stars were on the move while others had their uncertain futures cleared up. Here, we're going to dive into some of those moves and rank them in terms of the impact they could have for the 2023 season. That could be players that teams decided to add or — and maybe even more important in one particular case –players that they decided to lock up and keep in-house. 

10. 49ers land Javon Hargrave

Just when you didn't think San Francisco's defensive line could get any more dangerous, the organization cannonballs into free agency by singing Javon Hargrave to a four-year, $84 million deal. The 30-year-old is coming off arguably his best season in the NFL for the Philadelphia Eagles. He had 11 sacks, 10 tackles for a loss, and 16 quarterback hits while playing along the interior. Hargrave will be alongside Arik Armstead and Javon Kinlaw on the interior on a defensive line that will also have the Defensive Player of the Year in Nick Bosa firing off the edge. That's a sheer nightmare for opposing quarterbacks and offensive lines and should make the Niners front that much more lethal.

The only reason this addition isn't higher on this list is because it does feel like an embarrassment of riches for a defensive line that was already likely going to dominate again in 2023.
