Video: 10 Fantasy Football Questions You NEED Answered Before Week 2
CMC was dealing with tightness in the preseason...Kalin Black looked really good. Black played 43% of the snaps, led San Francisco with 14 carries. If Kalin Black is going to get double-digit carries every week, it's certainly going to lower the ceiling for CMC.

Rookie Kalin Black's 43% snap share and 14 carries threaten CMC's ceiling.

CMC dealt with preseason tightness and faced significant usage uncertainty in Week 1 with rookie Kalin Black receiving 43% snap share and 14 carries. While CMC maintains a high floor due to receiver usage (8 targets, 5 catches in Week 1), his ceiling is at risk if Black continues to get double-digit carries weekly. Goal-line opportunity split with Black remains a key variable for ceiling outcomes.
