At this point, I'm not too worried. Given the first two games were not exactly "offensive friendly", weather and opposing D, Pollard is currently 2nd on the Team in Yards from Scrimmage, behind only Lamb. If that remains, that will match 2022 when Lamb was #1 and Pollard was #2, and no one complain about Pollard last year.
Will Pollard wear down? Maybe. But IMO, if that does happen, that is a coaching issue, not a player issue. We overused Zeke early in his career and he inevitably broke down. The human body can only take so much punishment.
Now if the plan is not to bring Pollard back, then we can DeMarco Murrphy him and let him walk. If we plan on keeping him around, just try not to break him this year and spread the punishment around.
