NFL teams slashed their rosters to 53 players on Saturday, cutting around 700 men.
To call those rosters "finalized" in any fashion is categorically untrue. The cold truth of NFL life for players 48 through 53 on every roster is that their job is on the line each and every day. NFL rosters are like malleable hunks of clay, with the outermost edges constantly peeled off, moved, tossed away and reapplied where necessary.
The NFL's waiver period for players cut Saturday with less than four years of experience expires at noon ET Sunday, meaning another round of roster changes will take place.
Some teams have obvious additions that need to be made before the regular season begins.
Case in point: The Green Bay Packers initially needed a long snapper when the 53-man deadline passed. When the Packers announced their roster cuts Saturday evening -- suspiciously timed directly following the Wisconsin Badgers' upset win over LSU at Lambeau Field -- they did so with no long snapper.
On Monday, they eventually signed Brett Goode to fulfill the role, but the 36-hour void was a good example of how teams often approach roster cuts.
There are plenty of reasons teams might keep a player they know they'll probably cut later on. Some might want to remain heavy at a few positions then decide where depth should be after scouring the waiver wire. Injuries might play a part in whether one player makes it this week but is jettisoned after another heals. Or perhaps a team is hoping to sneak a youngster though waivers by cutting him later on in the process.
The point is, like the Packers, the roster changes aren't done coming in floods. Some of the moves are obvious. Others will surprise.
