Also MM explained that Spriggs is still feeling the effects of the broke knee cap he got in December, which normally takes 12 months to fully heal pain wise (though he's medically cleared). This might explain why they surprisingly switched Murphy over to LT (after MM talked about wanting to keep him on the right side) and they signed OT Bell even knowing Bulaga was ahead of schedule.
When GM Gute was asked about OG Madison coming to camp, Gute basically just ignored it and said they're more concerned about Madison (as a person) than worrying about football matters with him. Which leads me to believe he's going some extremely personal metal stuff.
Fan speculation has been all over the place, and NO ONE KNOWS... but I thought this speculation was interesting and might explain how all this came out of nowhere. THE FOLLOWING IS JUST SPECULATION by connecting different comments together, which potential could be unrelated.
According to a WSU photojournalist, Cole Madison and QB Tyler Hilinski were clearly best of friends on the field as they were ALWAYS together, always yelling out each other numbers and being silly on the practice field together. In mid-January, while Madison was in Florida doing football training, Hilinski without anyone's knowledge took a "former teammates" rifle, wrote a note and committing suicide. Madison was very well known for being a very avid hunter, had rifles, his stuff was probably still on campus and Madison MIGHT be considered a "former teammate" at that time.
Again, this is speculation. But I thought that would create some extremely personal metal problem for me.
