Brandon Marshall is going to need some extra time to integrate himself with his new teammates. New York Giants coach Ben McAdoo held the star wide receiver out of practice on Friday afternoon for "precautionary reasons." What that means is anyone's guess, from injury to personal reasons to rest to one of the receiver's many media obligations. Either way, it's not what the team was likely hoping for on Friday.

No Brandon Marshall at practice

According to McAdoo, some sort of soreness held Marshall out of Giants practice on Friday. What that soreness relates to is unclear, but he was spotted on the sideline, riding the stationary bikes alongside cornerback Eli Apple and tight end Rhett Ellison, skipping the day's drills.

Beyond that, there was no specific ailment cited for his time watching practice, instead of participating in it.

With the regular season still three months away, taking a cautious approach is not a bad idea for any team when it comes to injuries or ailments. Nevertheless, this is a valuable time where Marshall could be bonding with some of his new Giants teammates, including quarterback Eli Manning and fellow receiver Odell Beckham Jr. He and the team may look back at this time, regretting that Marshall was unable to take the field.

Final stop for Marshall

At age 33, this will almost certainly be the last career stop for Brandon Marshall. He signed a two-year deal with the Giants in the offseason after receiving his release from the New York Jets.

His desire to win for the first time in his career likely trumps all; with elite offensive weapons and a defense that has undergone huge changes in the past two seasons, he may have come to the right place.

Marshall has overcome plenty of demons in his NFL career, from mental illness to teammates who grew sick of his personality (see: Richardson, Sheldon).

The Giants have their own baggage coming into the season following a massive playoff exit, potentially triggered in part by a trip to Miami taken by some of the receiving core prior to the playoffs. The mini-vacation didn't lose the team the game, but the optics of the situation were poor and pervaded in the media to this day.

Only time will tell if the relationship between a controversial receiver and a sometimes controversial team will work out. If it does, the

Only time will tell if the relationship between a controversial receiver and a sometimes controversial team will work out. If it does, the Giants should be ready to make the playoffs once again and make an even deeper run than they did last season.
