Lack of experience probably isn't a bad thing either, considering it's not really a position that requires it.
An unseasoned MLB is a sitting duck as he's going handle communications. When the see a look he can exploit we're stuck with whatever the DC sent in. Even if an offense show a vulnerable look we can exploit that inexperienced MLB doesn't have the IQ to pick up on it ,communicate it ,or audible out. MLB isn't all about brawn and stats.
