Probably the only way it would really be fantasy relevant is the following two scenarios:
Chol filling the spot - Means less ruck time, means more ruck time for Witts.
Lukosius filling the spot - Completely sinks him as a fantasy option but might open more rebounding work for the guy who gets the rebounding role instead.
Tend to agree with
@Leroy that any other scenario is just going to be a nothing role, probably someone like Jeffrey last year who managed a whopping 26 average across his 4 games.
