D$ compares him to Brandon Flowers, which I agree with from a measurables & play style standpoint.
I compared him to Tavon Young out of Temple, who is built like Bandy & has close to identical measurables as well. Young was a 4th round pick after being a 4 year starter in college & put up similar numbers.
He's been a very good Nickel Corner for the Ravens he's already signed a 3 year extension for $25mill with $13mill fully guaranteed. They didn't even let him get to the final year of his rookie deal, they extended him after just 2 years in the league & that's even after he missed a whole season with a ACL.
Young benefitted from coming back his Senior year & has already been more successful than 1st rounders that were drafted ahead of him like Eli Apple & Vernon Hargreaves. Bandy would most likely go Undrafted if he came out after this season, unless he had an insane year where he got like 10+ PBU's & 7INT's, then he'd probably get bumped up a few rounds. But otherwise, if Bandy leaves early he'll be a low round at best & most likely UDFA.
He needs to come back his Senior year if he wants to get picked in any rounds higher than 6th or 7th, look no further than Corn Elder. Elder his Senior year had 76tcks 4.5 TFL's 3 sacks & 12 PBU's & was still only a 5th round pick.
