The big off-season question surrounding the Saints, who will emerge as another receiving threat? While that questions is still unanswered, a couple of players are starting to impress. WR Keith Kirkwood had a solid day turning in a few nice catches, prompting praise from Bobby Hebert, "He's a silent assassin. Kirkwood doesn't say much, but you know why Drew (Brees) likes Kirkwood? Because he trusts his route running," explained the former Saints quarterback. "He's steady and reliable,” Hebert added. Rookie tight end Alize' Mack caught the attention of the Cajun Cannon as well, “He had like four or five catches today. You can see how athletic Alize’ Mack is for sure," Hebert emphatically stated.
