Ryan hasn't really earnt the right to play in the 2015 Grand Final, but he has earnt the right to play in the 2015 Prelim Final and break a few heads.
That is essentially his and Lyon's choice. If Ryan plays and doesn't get suspended the following week, he won't have done his job properly.
If I were Ross, I'd say to Ryan, take out at least one of Mitchell, Hodge, Lewis or Gibson and although you'll be rubbed out, I'll give you the chance to play your 200th game in 2016.
