Jobs are on the line at training camp this year and every year. Every roster spot must be earned no matter the player’s history.

Here are three who especially need a good training camp:

1. Kyle Van Noy just didn’t get much of a chance to prove himself in 2014, his rookie season. The pass rusher was injured in the preseason, missed the first eight games and then saw mostly special teams action when he returned. Heck, the defense was No. 2 in the NFL so it was hard to knock anyone out of his spot at the time. Van Noy and Tahir Whitehead will battle for the outside linebacker spot opposite of DeAndre Levy. Whitehead has the edge in experience. It could be a season of mostly special teams for Van Noy, a second-round pick. Still he has to prove he is worth even that.
   
   
2. Ryan Broyles is not coming off a major injury for the first time since he was drafted in 2012 in the second round. He’s looked fine in OTAs and minicamp, but he faces good competition among wide receivers. Last year he seemed healthy and cracked the 53-man roster but was active for just five games and had two receptions for 25 yards. He had a head-turning showing in the 2014 preseason games so it was a bit of a mystery why he didn’t get more playing time when it counted.
   
   
3. TJ Jones sat out his whole rookie season following shoulder surgery. It’s made the wide receiver that much more hungry this offseason. He started to stand out more often in the three-day minicamp where he returned punts and kicks along with Broyles and Lance Moore. Broyles and Jones could both make the 53-man roster, but the competition is tight.
