At least the good part of red shirting a senior on the big draft board is that with the WE drop, his ratings won't improve or will drop as well. But he's probably treated as any other senior. If he gets drafted he's gone, but if he stays, he'll be there next season.
There is no "likely going" "on the fence" or "likely staying" with seniors, it's just listed as graduating, so no idea on what the odds are.
