There’s time to sort things out, and given the nature of training camp and the exhibition games, injuries are bound to happen. But as the Red Wings prepare to open training camp Friday, there appear to be one too many defensemen. General manager Ken Holland said this summer the plan is to carry seven — which could leave a young defenseman like Ryan Sproul in danger of not making the roster. With Trevor Daley, Danny DeKeyser, Jonathan Ericsson, Mike Green, Nick Jensen, Niklas Kronwall and Xavier Ouellet seemingly secure of spots, Sproul could be the odd man out. Sproul, 24, saw his season ended in early March when he suffered a knee injury that ultimately needed surgery. Whether Sproul will be ready to begin the regular season Oct. 5 remains to be seen. In 27 games last season, Sproul had a goal and six assists with a minus-8 rating.
