You don't care about my opinion yet you're still here asking me questions
This is for free: Bandy played a safety position "in name" last season IF IF IF Manny was calling it a 4-2-5 defense. Why? Bc in a traditional 4-2-5. Outside of the corners, the remaining DB positions are called Free Safety, Weak Safety, and Strong Safety...this is terminology from the man that essentially invented/perfected the 4-2-5(Gary Patterson), some DC's call it Rover/Bandit/Bull/Hulk/Superman...depends on the DC. If Manny was calling it a nickel defense then Bandy was the nickel..a nickel can be either a safety or a cb. Just depends on the terminology.
Now of course your pre-school equivalent knowledge of football would say the position he's listed at on the roster (CB) is the position he's played last season but I expect that from you.
Next time I'm charging...
