ST. JOSEPH, Mo. (AP) – Kansas City Chiefs wide receiver Jon Baldwin is determined not to let his return to training camp bring back bad memories. A locker-room fight last August with then-teammate Thomas Jones left Baldwin with a broken right hand, an injury that derailed the first-round pick’s rookie season.  Nearly a year later there are still more questions than answers as Baldwin participates in camp on the same Missouri Western State University campus. Still, Baldwin prefers to talk about the future not the past. Baldwin entered camp this week as the Chiefs’ de facto No. 1 wide receiver due to Dwayne Bowe’s holdout.  That slot asks a lot of a second-year player limited to 11 games in 2011 due to the lingering injury. Baldwin had only 21 catches for 254 yards.
