John Lynch’s latest comments have put Isaac Guerendo’s spot on the 49ers’ running back depth chart in serious doubt. Despite a solid rookie season, Guerendo now finds himself slipping to No. 3 after the team traded for Brian Robinson Jr. and continues to show strong faith in rookie Jordan James. Lynch even hinted James could leapfrog Guerendo once healthy. With competition heating up and every practice rep counting, Guerendo has to prove he still belongs. How do you see the 49ers’ backfield shaping up this season? #Sports #Football #49ers
