As the Chiefs hold their final offseason practice open to the media this morning, we reflect on some memorable moments. And some that were not so memorable. That's the way it has gone this offseason so far, with some reasons for optimism and some concerns, too. Some problems seem to have dissolved, and others have been overshadowed. Some problems just don't seem to be getting much better.

After two months of OTAs, here are 10 players who left an impression -- for better or worse.

THE GOOD

- QB Matt Cassel. The new Chiefs quarterback is accurate, poised and ready to call a team his own for the first time since high school. Cassel's accuracy is a welcome change in Kansas City, but the 27-year-old's tests will begin in training camp, when the offensive line has to address its problems and try to find some cohesion with or without Brian Waters.

- LT Branden Albert. He reported to practice overweight, which isn't so good, but then he proceeded to lose the extra flab and a whole lot more. As of last week, Albert has lost more than 30 pounds since March. Coach Todd Haley talks about Albert as if the lineman possesses elite talent.

- LB Zach Thomas. The veteran linebacker might have left the biggest impression, particularly on his teammates. Each defensive player discusses the level of influence Thomas has had over this young group, and Thomas is becoming the clear leader on a unit that was starved for leadership last season. It doesn't hurt that he has lots of experience playing in the 3-4 defense, something most Chiefs defenders cannot claim.

- CB Maurice Leggett. It would be so easy to overlook Leggett, whose small frame and unlikely trip to the NFL make him an unusual fit in Kansas City's talented secondary. But Leggett continued to display that he has a nose for the ball, picking off Cassel twice in a day during the team's minicamp. His best chance to start remains at nickel, but he'll have to keep it up to fend off rookie Donald Washington.

- G Mike Goff. The veteran lineman was brought in to possibly replace Brian Waters, and for the Chiefs' sake, it hopefully won't come to that. Regardless, Goff will find a place to fit into the lineup, and his experience and skills represent a clear upgrade over last year's right guard, Adrian Jones.

THE NOT-SO-GOOD

- DL Glenn Dorsey. This might be a bit unfair because he's a man without a position, most likely shifting from defensive tackle to end, which is an odd move for last year's No. 5 overall pick. But Dorsey also has barely practiced this offseason, instead spending most of his time on the rehab field. Dorsey hasn't revealed what his injury is or was, but he returned to practice late last week. Dorsey has lots of work to do before he proves himself to be a reliable starter, let alone a player who lives up to his draft slot.

- WR Dwayne Bowe. The drops continue, and it has grated on coach Todd Haley's nerves. Bowe seems intent on making spectacular attempts instead of routine catches, and that doesn't fly in Haley's world. Bowe has toned down his look-at-me act, but he has to do better on fundamentals.

- LB Tamba Hali. Again, maybe not fair because Hali is moving from defensive end to linebacker, but that's what is in his future. The former first-round pick looks out of place at linebacker, although he has made the best transition of the others who made the move from the line. Hali has months to add polish, which his outstanding work ethic suggests he'll do, but he already has been running with the first-team defense, which adds lots of pressure to the fourth-year defender.

- TE Brad Cottam. It's early for the second-year tight end, but Haley said last week that Cottam hasn't grabbed the starting job as it was expected. The tight end job remains open, and that has as much to do with Cottam's dropped passes as several other players' emergence. For the man charged with taking Tony Gonzalez's spot, no pressure, kid.

- The other wide receivers. We singled out Bowe because he's a first-round pick entering his third and pivotal season, but the other wideouts haven't done much to inspire confidence in what could be a tough offense to watch at times this season. Cassel will have his work cut out, behind a patchwork offensive line and with a group of unreliable targets. Drops continue to be a noticeable and disturbing issue, and that's something the Chiefs must address and fix in the preseason.
