With the free-agent signing period scheduled to begin in a month, it is clear the 49ers must make a decision on Reuben Foster. It does not have to be a dramatic decision. After all, it appears the 49ers are willing to take their time to let the investigation unfold before determining whether Foster will still hold a spot on the team’s roster. The 49ers must approach free agency and the draft as if Foster is a person who can no longer be counted upon to be a long-term member of the organization. Foster talked multiple times on the phone and in person on Monday with 49ers general manager John Lynch and coach Kyle Shanahan, according to a source. He is also said to be cooperating fully with the investigation – both at local law enforcement and NFL levels. The 49ers acted swiftly a year ago when Lynch and Shanahan were faced with a decision after Tramaine Brock’s arrest after an alleged domestic incident. Shortly after meeting with Brock, the organization released Brock. (Brock did not face formal criminal charges after the Santa Clara County District Attorney’s office concluded it lacked sufficient evidence to seek prosecution.) The organization has not been as decisive with Foster, a player in whom the 49ers invested a first-round draft pick to acquire. It appears as if the 49ers believe there are enough unknowns and gray area to let the situation play out.
