NAPA -- Some highlights from a morning practice session that included the first live sequence with tackling to the ground of training camp:

  • There was more sloppiness than coach Dennis Allen would have liked in the early portion in practice, including offsides penalties by Lamar Houston, Dominique Hamilton, Travis Goethel and Carl Ihenacho, dropped passes by Brandon Carswell and Tory Humphrey and an unforced fumble by Lonyae Miller.

    Allen said those issues would be addressed during meetings as mistakes that are costly in the NFL.

    "The first thing you've got to learn is how not to beat yourself," Allen said.

  • Defensive tackle Richard Seymour sat out his second straight practice with a sore knee, but it's more about rest than the injury, according to Allen. Punter Shane Lechler is at least a week away as he rehabs a sore knee.

    In the meantime, free agent Marquette King hits some punts with a Lechler-like height and distance but has issues with consistency.

  • In the first live session of camp (tackling to the ground was allowed, the lone restrictions were no cut blocking or hitting the quarterback), the offense got the better of the defense in short yardage situations.

    Miller gained tough interior yards and swing passes by Carson Palmer and Matt Leinart gained yards. Leinart got one big yardage pass to Mike Goodson down the left sideline.

    Goodson continues to assert himself as the primary backup for Darren McFadden.

  • Nice short-yardage run by Owen Schmitt, who will compete for a Zack Crockett-type role.

  • What looked as if it could be a platoon situation at tight end instead looks like Brandon Myers could seize the role of full time starter, with David Ausberry coming in occasionally in some packages and Richard Gordon primarily as a blocker

    Myers has shown a nice feel for offensive coordinator Greg Knapp's offense, which made heavy use of tight ends in the receiving game when Knapp was quarterbacks coach in Houston.

  • Lots more work than expected for cornerback Ron Bartell, who practiced without shoulder pads but was on the field a lot. He can't practice with pads until Wednesday.

  • Cornerback Shawntae Spencer made a nice breakup of a deep pass which was intercepted by Matt Giordano out of bounds.
