I'm no good at replying to posts in chunks like you are, and I don't want to risk the format issues.
I don't know the details of what got Pilgrim and Penn suspended, if they were ego caused or academic or lateness to team meetings or what, or how detrimental to the team they were. Even with Penn around all year, I don't think this team gets another win. The real negatives were losing Gulley to injury in November and D. Williams rape charge. I think a definite argument could be made that, that was poor evaluation on Ford's part. I have no idea if D. Williams was a known trouble maker or malcontent before stepping on campus. But, sometimes you just get burned.
As far as why players leave, I don't know if egos play a big role in that. I think Ford (for better or worse) has a quick trigger when getting rid of players and signing new ones, see Mssrs. Walker, Akol and Kirkland.
My main (original) point is that having a sub .500 with one McDonald's AA talent (let alone 3) is not the norm, and be it just flat out bad luck on Capel's part or mismanagement from the get-go and things just snowballed after that on him, the odds are in favor of Ford being more successful with his egos than Capel was with his.
That's not because I think Ford has some inherent and identifiable advantage over Capel with handling egos, but rather I think Capel's experience was such an outlier that it will be tough for Ford to NOT do better than that, and maybe exceptionally better, and I'd feel the same about just about any coach.
I just think talent overrides chemistry, particularly when that talent is winning. Now, if OSU hit some bumps in the non-conference schedule like OU did last year, then who knows what could happen. But, if I were betting, I would bet against it.
