On March 16, NFL news not involving the lockout broke when it was learned that the league was looking into changing a few rules regarding kickoffs and replays. Almost a week later and those rule changes are now made good.
Kickoffs will now be at the 35-yard line instead of the 30-yard line. This does not bode for kick returners like Devin Hester since touchbacks will become more prevalent now. One rule that was discussed but not adopted was moving the touchback line to the 25-yard mark. Had that one passed, one could almost imagine no kickoff returns unless the kicker messed up on the kick and had it land short of the end zone.
All scoring plays will now be reviewable by the booth instead of just in the final two minutes of each half. There was a possibility of eliminating a team's third challenge if the previous two challenges were in favor of the team, but it was defeated. According to Mike Klis of the Denver Post, Broncos head coach John Fox and Patriots head coach Bill Belichick led the fight to keep that rule in place.
The field color for any NFL playing surface must be a shade of green. This is likely a result of Boise State having a blue field and Eastern Washington a red turf.
But without a new Collective Bargaining Agreement, these rule changes are just floating out there right now.
