"It was not as sexy as his statistics or as thrilling as his 35-yard touchdown catch, but Brent Celek's blocking in the Eagles' 34-14 flogging of Kansas City on Sunday illustrates best how he has become a complete tight end.Even though he started the final four games last season, critics suggested that Celek's supposed deficiencies in run blocking warranted an upgrade at the position.It's funny how three games can alter the discourse. The third-year player leads all NFL tight ends in receptions and receiving yards, and his blocking has improved dramatically."He's really worked on his run-game [blocking] also, and he's doing a better job there than he did last year," coach Andy Reid said. "That's something that I thought he could improve on."The best example came on the Eagles' first scoring drive, a series in which Celek did not even have one of his team-high eight catches.After the Eagles drove to the Chiefs' 34, Michael Vick was inserted in the team's "Spread Eagle" package for the first time. He took a direct snap and ran the option to his right with Jeremy Maclin trailing. Rather than pitch to his receiver, Vick wisely kept the ball and followed Celek's lead block. Celek pushed linebacker Mike Vrabel for the entire length of Vick's 7-yard gain, never giving up.Two plays later, Celek was lined up on the left side, with tight end Alex Smith flanking the right. Chiefs linebacker Tamba Hali stood opposite Celek and rushed outside. Celek guided Hali wide, forcing him to overrun LeSean McCoy, who shot through the initial hole. The running back did the rest, cutting once and scooting 14 yards to the 5-yard line."
