I think Cox and/or Murray (dare we dream for a wrinkle in the offense of bringing in a different type qb once or twice in an offensive series to keep defenses guessing?) would fill the void for MS better than CK or RS would for KM, so if one stays, I vote Knowshon. Plus I don't think he's quite as ready to succeed in the NFL as Stafford is.
The SMART era CONTINUES!!!!!!
