Marcus Robertson said the three things that enticed him the most about becoming the Lions' new defensive assistant/secondary coach were head coach Jim Schwartz, quarterback 
That's an interesting top three coming from a coach whose main focus will be the secondary.
"I'm excited with what Jim (Schwartz) is doing up here in Detroit," Robertson told Detroitlions.com.
"The other thing was the opportunity to be with an elite quarterback. In this league, you have to have a quarterback to give you the ability to put points on the board.
"I also looked at the fact that they have one of the best defensive lines in the NFL. If you can rush the quarterback with four (players), you'd be amazed what you can do in the back half."
Robertson is smart enough to know that it's hard to win in the NFL without the right coach, being able to throw the football and being able to rush the quarterback. Everything beyond that is what separates the good teams from the really good ones.
As for the players Robertson will help to coach, he said he's especially excited to work with safety
Robertson played 12 NFL seasons at safety after being drafted out of Iowa State in the fourth round by the Houston Oilers in 1991. He was an All Pro in 1993 and 1997 and played in 157 games (144 starts) with 851 tackles, 24 interceptions and 1.5 sacks.
"Marcus played 11 or 12 years in the league, was a Pro Bowler, and has a lot of experience," said Lions secondary/third down package coach Tim Walton. "He brings playing experience in the league as well as coaching experience. He's had a chance to coach a lot of good players."
Robertson joins the staff for his 22nd season in the NFL and his sixth season as a coach. He has coached the past five NFL seasons with the Titans where he started as an assistant secondary coach (2007-08) and finished as their secondary coach (2009-11).
Robertson said his coaching philosophy is simple and predicated on technique, discipline, and tackling, which should make him feel right at home with Schwartz and defensive coordinator Gunther Cunningham.
"I just want to get these guys here to play with more consistent technique and put them in a position to make more plays on the ball," Robertson said.
"I think if we go out on the field every Sunday and have a good understanding of how offenses want to attack us and play with some consistency and technique, we'll be in a position to make more plays and have more opportunities.
"We have to be a much better tackling football team and that goes back to understanding the importance of every single play and every single yard and being in a position to make it easier for a defensive coordinator to make a call."
The chance to reunite with Schwartz and join an up-and-coming team in the Lions was ultimately too enticing for Robertson to pass up.
"The way they've turned things around the last couple years, I think this is definitely a team that has a chance to win a Super Bowl and I'm hoping I can come here and relay the message of the head coach and the defensive coordinator and hopefully add value to what Tim (Walton) has already done with the secondary," he said.
