No other Titans player fighting for a roster should be getting more attention than Marc Mariani, who made the Pro Bowl as a returner in his rookie season in 2010 but missed the last two seasons with injuries.
Some may think that Mariani's place on the roster for 2014 is secure, but I would have to disagree.
There's not a ton of room for him on the roster as a returner with Leon Washington and McCluster also viable returners. It's my belief that Mariani has to make the team as a wide receiver, and he has some stiff competition in that area.
Michael Preston's roster spot should be secure as the No. 4 guy. His athleticism and his ability to make big catches makes him safe.
As for Mariani, he's familiar with the feeling of being on the roster bubble, per Joe Fann of the Titans official website.
It was unfortunate that Mariani couldn't haul in that red-zone pass from Zach Mettenberger against the Saints. It would have been a touchdown and could have really given this coaching staff something to chew on outside of Mariani's special teams ability.
The main guy whom I could see taking Mariani's job is veteran Brian Robiskie. He's been close to perfect in practices and preseason. He's sprinkled in a couple of great catches and would bring some much-needed veteran experience to an otherwise young group.
Derek Hagan is another veteran who has an outside chance to make the roster if he finishes out the preseason in strong fashion.
Mariani needs an efficient outing as a wide receiver to prove that he's worth a valuable roster spot.
