The best thing for Oakland, IMO. Is easily Teddy Bridgewater. Draft the QB and then target WR, O-line in rounds 2,3... Address the defense with free agency.
Teddy Bridgewater, QB
Davante Adams, WR
Dakota Dozier, OG
Add these rookies to the young talent already on the team like Latavius Murray, Rivera, Streater. Raiders could have a young up and coming offense. They have to devlop these guys. Build an identity, starts with the QB.
