DALLAS COWBOYS (8-8)CAMP SITE: Frisco, TexasLAST YEAR: Season with high expectations ended without playoff spot, leading to departure of coach Jason Garrett. Mike McCarthy, Super Bowl winner in Green Bay a decade ago, took over. IMPORTANT ADDITIONS: McCarthy, WR CeeDee Lamb, DT Gerald McCoy, DE Aldon Smith, DT Dontari Poe, S Ha Ha Clinton-Dix, CB Maurice Canady, K Greg Zuerlein. McCarthy won Super Bowl with Aaron Rodgers, but hasn't had chance to get to know Prescott face-to-face. EXPECTATIONS: Cowboys still believe they have roster capable of contending for Super Bowl, but patience might be required based on circumstances.
