2012 NFL Preseason: 5 Observations from Thursday's Nights Action

The 2012 NFL preseason showcased six games on Thursday, with Robert Griffin III and Chandler Jones receiving the majority of the attention early on.

With 11 teams playing in their first preseason games tonight, there is obviously plenty of time for players to adjust to new systems and to get back into game shape.

However, the opportunity to watch players find success early on in the preseason could lead to future success in the upcoming season.

Here are five observations from the early portion of preseason action.

5. The New Referees Are Going to Be a Problem

The NFL replacement referees have not exactly received the warmest welcome, and tonight's major miscues won't help their cause.

First, they ruled a touchback in the Bills-Redskins game where the player downed the ball at the four-yard line. Unfortunately, the Redskins had no choice but to use one of their available challenges.

They also called an unsportsmanlike penalty on rookie Nick Perry who simply flexed after recording a sack.

In fact, the referees even managed to call a flag on the Arizona Cardinals in the Ravens-Falcons preseason game.

The biggest question of the preseason is if the NFL will be able to agree on a deal that will ultimately allow the return of the normal NFL referees.

4. Pittsburgh Steelers' Young Offensive Line Has a Long Way to Go

The Pittsburgh Steelers are among many contending teams that are adjusting to a lot of change on the coaching staff and the current roster.

In 2012, the Achilles heel will clearly be the offensive line for the Steelers, who are expected to start two rookies this season.

The young offensive line faced a major test early on against a Philadelphia Eagles defense that has put plenty of pressure on the quarterbacks in the past. 

Ben Roethlisberger faced a ton of pressure early in the game, as David DeCastro and Mike Adams started for the first time on an NFL field. Adams also left the game with a minor injury.

As teams continue to prepare for the upcoming season, the Steelers' offensive line must continue to focus on building chemistry before the regular season.

3. Robert Griffin III Took Control of the Redskins' Offense

Robert Griffin III made his debut tonight against the Buffalo Bills and had a solid first outing.

Facing an improved Bills defense, Griffin completed 4-of-6 passes for 70 yards and a touchdown. Clearly, he was comfortable throwing to former Colts receiver Pierre Garcon.

Garcon recorded three receptions for 58 yards and a touchdown. The Redskins must be pleased with the good start by Griffin early on in the season.

2. Chandler Jones Already Make an Impact on the Patriots' Defense

When Chandler Jones was selected by the New England Patriots in the first round this year, the former Syracuse standout was expected to be a project defensive end who wouldn't be a huge surprise in his first NFL season.

That proved to not be the case in the Patriots opener vs the Saints. The athletic Jones faced up against Jermon Bushrod and forced two holding penalties against the veteran offensive lineman.

The Patriots defense needs to improve as a whole, but Jones could be a pleasant surprise by providing pressure on opposing quarterbacks on a weekly basis.

1. Julio Jones Was Unstoppable Against the Ravens' Secondary

Julio Jones is poised for a breakout season with an Atlanta Falcons offense that is going to be up-tempo with the passing game.

He faced a test early against a Ravens secondary that featured Lardarius Webb and Cary Williams.

It was evident that Jones wasn't fazed at all. He recorded six receptions for 109 yards and one touchdown against the Ravens, who couldn't stop the former first-round pick.

New offensive coordinator Dirk Koetter is already orchestrating an explosive offense in the works with the Falcons.
