<strong><span class="subhead">The education of a rookie</span></strong></p><p>Rookie running back Jamaal Charles got a lesson early in practice Wednesday. The Chiefs were running what they call the four-minute drill in which the offense attempts to kill that amount of time off the clock. The drill is designed to allow the Chiefs to work on protecting a slim lead late in the game.</p><p>Quarterback Brodie Croyle threw a swing pass to Charles, who inexplicably ran out of bounds to stop the clock. The prudent move was to allow himself to be tackled on the field of play so either the clock would advance or the defense would need to call a timeout.</p><p>Charles immediately realized his mistake and told his coaches, &#8220;My bad,&#8221; but that explanation wasn&#8217;t good enough for offensive coordinator Chan Gailey, who got into Charles&#8217; face.</p><p>&#8220;You don&#8217;t have to tell me it&#8217;s your bad,&#8221; Gailey screamed almost loud enough to be heard back in Kansas City. &#8220;I know it&#8217;s your bad.&#8221;</p><p><strong><span class="subhead">A lot to live up to</span></strong></p><p>The Chiefs set some high expectations for their offense in last week&#8217;s preseason opener against Chicago by going on a 16-play, 81-yard TD drive and chewing up almost nine minutes on their first possession.</p><p>While quarterback Brodie Croyle wouldn&#8217;t necessarily turn down another, similar opening drive in Saturday&#8217;s game against Arizona at Arrowhead Stadium, he said the first possession wouldn&#8217;t define whether the Chiefs have offensive success.</p><p>&#8220;Just us go out there and find a way to score some points on the first drive,&#8221; Croyle said when asked what would indicate whether the Chiefs are making progress. &#8220;Then come out there and do it for two, three, four, you know, however many series we&#8217;re going to have. Don&#8217;t have any three-and-outs. That&#8217;s something we can&#8217;t have.</p><p>&#8220;There isn&#8217;t one scenario that&#8217;s a perfect scenario. Obviously you want to go out there and score a touchdown every time, but they get paid to play defense just as much as we get paid to play offense, so it&#8217;s not going to happen every time. But if we get better and correct some of the things we had mistakes on against the Bears, we&#8217;ll feel like we had a pretty good second preseason game.&#8221;</p><p><hr class="infobox-hr-separator" /> <div class="infobox"> <strong><span class="subhead">What you need to know about ...</span></strong></p><p><strong><span class="infobox-head">THE OFFENSE </span></strong><br /> Tight end Tony Gonzalez received no love from the officials the Chiefs hire for practice. First, Gonzalez was ruled out of bounds on a sideline catch from Croyle, prompting the agitated Gonzalez to tell the official, &#8220;You&#8217;re wrong.&#8221; Later, Derrick Johnson interfered with Gonzalez to break up a pass, but no penalty was called. &#8230; Dwayne Bowe caught a touchdown pass from Damon Huard on a stop-and-go pattern and beat rookie cornerback Maurice Leggett, who fell completely for Bowe&#8217;s fake.</p><p><strong><span class="infobox-head">THE DEFENSE </span></strong><br /> The Chiefs are sending linebacker Demorrio Williams after the quarterback frequently with good results. He would have had a sack on one play had tackle Anthony Alabi not tackled him. &#8230; At 5 feet 9 and 187 pounds, rookie cornerback Brandon Flowers yields eight inches and 64 pounds to Gonzalez, but that didn&#8217;t matter when Flowers went up high to break up a pass intended for the larger receiver. Almost as if to prove a point, Croyle went right back to Gonzalez on the next play and this time connected with Gonzalez with Flowers in coverage. &#8230; Safety Bernard Pollard had the hit of practice when he leveled running back Kolby Smith.</p><p><strong><span class="infobox-head">INJURY REPORT </span></strong><br /> Wide receiver Kevin Robinson (knee), offensive linemen Branden Albert (foot) and Damion McIntosh (knee), defensive linemen Trevor Johnson (concussion), Brian Johnston (hamstring) and Turk McBride (hamstring), linebackers Donnie Edwards (hamstring) and Napoleon Harris (knee) and safety Jon McGraw (shoulder) did not practice.</p><p><strong><span class="infobox-head">TODAY&#8217;S SCHEDULE </span></strong><br /> The Chiefs will have their final practice in the Wisconsin portion of training camp.</p><p></div>
