1. Jeremy Kerley wasn't surprised that he was relegated to backup duty -- after all, he hadn't been practicing with the first-team offense in his usual slot role -- but he seemed a bit perplexed as to why it's playing out like this. He said it "felt really weird," speculating the new coaching staff still doesn't have a feel for him yet. He missed time during the offseason because of an Achilles' injury. "We have new coaches and they didn't get to see a lot of me," said Kerley, who had no receptions (two targets). Todd Bowles said he wanted to give Quincy Enunwa a look as the No. 3 receiver. Enunwa dropped his only target in the game. Kerley didn't want to make a stink. As he said a few times, "I'll let my play do the talking."
2. It was a non-descript debut for No. 1 pick Leonard Williams, who started at defensive end (no surprise) and played three series. The former USC star didn't make the stat sheet -- no tackles. Williams said he didn't play enough to give a self-evaluation. The one thing he acknowledged was the NFL is more cerebral than the college game. "It definitely has surprised me, especially the D-line position," he said. "(In college), you play alignment and find the ball. Now we have to make sure we play our gap and we slant to the right spot. There's more things to do in the NFL." Welcome to the bigs, kid.
3. Naturally, Bowles was upset with the poor tackling. By my count, they had at least seven missed tackles, and that's probably on the conservative side. They were gashed on the first series, as Antonio Cromartie, Calvin Pryor and Marcus Gilchrist had misses. Later, Demario Davis was juked by rookie running back Ameer Abdullah, whom Bowles said is "about as quick as Barry Sanders." Bowles said they will focus on tackling in practice this week. In case you're wondering, Bowles didn't call the defensive plays. He left that to coordinator Kacy Rodgers.
4. There were two injuries of note -- tight end Jace Amaro (shoulder) and linebacker Eric Henderson (knee). Henderson said he has a sprained MCL, adding that he will have an MRI on Friday. Henderson, making a strong bid for a roster spot, was having a nice game (four tackles) before he was hurt. He's competing with Joe Mays, who produced a team-high seven tackles. Bowles didn't have an update on Amaro, who got no work in any of the first-team offensive packages.
5. It was a humbling night for the demoted Sheldon Richardson, who came off the bench and played only in the second quarter. "I brought it on myself, so I have to handle it," he said. He was referring, of course, to his four-game drug suspension and recent arrest -- an apparent violation of the league's personal-conduct policy. Richardson, facing a potentially longer suspension, said he hasn't heard from the league yet.
