Well, your PARTLY right....
The reason they are able to play in the Bowl game is due to the fact that the NCAA wants to make thier PRECIOUS MONEY.
Without those players playing, many would not be tuning in .... I don't care if it's the #1 team in the nation, you sit 4 guys off your offense and they will lose and attendance will dwindle, attendance dwindles, so does the amount of money changing hands, hence, no wheres near the money that would normally be coming in.
I don't think a "Deal" as you put it had anything to do with it.
Fwiw, there was a good chance that 4 of the 5 players would have been coming back next year, seeing they all came into the Buckeye's the same time.
Now, I would not be surprised to see all of them leave, mainly because the NCAA is FORCING them too.
What point would it be to play only 1/2 your teams games the next year.... pretty much a waste of a year, why bother.
That said, I would not be surprised to see this appealed and reduced at least one game maybe more.
