I think they'll try to move the twins, charges or not. Markieff is on a great contract, Marcus' deal is not prohibitive. They're suspects in an assault case, even if it ever goes anywhere (which seems dubious) the league would likely slap them with a 3-5 game suspension and thats the end of it.
This screams buyer beware to me. What do you think a team would actually give us for the Morri?
