The first week of training camp wouldn't be complete without the concomitant holdouts.

As the Rams report for duty, All-Pro defensive lineman Aaron Donald is in search of a life-changing contract. One of the , Donald has been in the league over the past two seasons.

Due to transition from a three-technique defensive tackle to defensive end in Wade Phillips' 3-4 scheme, Donald is smart to strike now in case the position switch meets an adjustment period. We suspect the Rams' most valuable building block will end up surpassing Ndamukong Suh as the league's highest-paid defensive star.

While Donald's stance comes as little surprise, the holdout of Raiders left tackle Donald Penn was not expected. The stalwart blindside protector for $125 million quarterback Derek Carr, Penn allowed just one sack last season -- the one that led to Carr's broken leg.

At this point, Landry is expected to , ¹ú²ú̽»¨Network's Tom Pelissero reported. With DeVante Parker and committed to Kenny Stills, it's no surprise that Miami would be reluctant to shell out top-tier money for a slot receiver -- even a premier one.

Deja Vu

1. Two summers after Mychal Kendricks first began to in Philadelphia, the veteran linebacker revealed that he requested a trade this past offseason. The Eagles promptly , citing Kendricks' youth (26 years old) and talent. The older brother of Vikings linebacker Eric Kendricks signed a with the Eagles in August of 2015.

2. Steelers president Art Rooney II never took Ben Roethlisberger's offseason seriously, chalking it up to "" stemming from the AFC Championship Game loss to the Patriots.

5. The Friday afternoon news dump came and went without word of Ezekiel Elliott discipline, but not all Cowboys avoided the long arm of the NFL's law. Defensive lineman Damontre Moore has been for violating the ¹ú²ú̽»¨Policy and Program for Substances of Abuse. Dallas' defensive front is going to be short-handed to start the season.
