_Including trades, free agents and rookies, which offseason additions do you think made the_ _biggest_ _impact at Philadelphia? Kenny Clark looks to be a very nice addition, and if the weather was better, I think George Pickens would have racked up at least 70 to 80 yards receiving. Who made the biggest impressions on you?_ **– Danny Whitehouse/Kingsland, TX**
**Mickey:** Let me hold myself to two, since there were a slew of new players making an impact in the season opener, including the two you mentioned. Why don't we go with linebacker Kenneth Murray, who led Tennessee with 95 tackles last year, playing in just 14 games. He started off his Cowboys career with a bang, tying for the team lead with nine tackles against the Eagles, and a sure bang for the Cowboys giving up merely a sixth-round pick to the Titans for Murray and a seventh in return. Also, first round draft choice Tyler Booker, holding his own starting at right guard against a stout Eagles defensive front, despite the loss of ringleader Jalen Carter. Booker played physical and was part of a Cowboys offensive line with all five starters playing together in a game for the first time. The Eagles did not sack QB Dak Prescott even once and only registered one quarterback hit, though got to love him saying this week, "I still need to improve on a lot of things."
