NFL players' March musings on Twitter aren't necessarily the gold standard for information, but Randy Moss' comments Saturday line up with expectations the team will go with younger players at the position in 2013."Wished we could've finished the job!!thanks for the opportunity an good luck in the future 9ers," Moss' Twitter account said.Moss is 36 years old. He provided value to the 49ers during a transitional season at wide receiver. The team needed him more than anticipated once an injury felled Mario Manningham.
