The Jaguars begin training camp this week. Here are players and key position battles to watch -- and a 53-man roster projection.

Competing for that playing time are Darnell Savage, Caleb Ransaw, Andrew Wingard, and Antonio Johnson. The Jaguars also have rookie Rayuan Lane, who could help on special teams right away, and Daniel Thomas, who has been a core teams contributor for the Jaguars.

With NFL training camps just around the corner, Coral Smith provides a refresher on the Jacksonville Jaguars' roster changes, position battles and notable subplots.
