The Raiders were busy Wednesday, not only having former Washington State linebacker Frankie Luvu in for a visit but also hosting former Louisville cornerback Jaire Alexander for a pre-draft visit, according to USA TODAY’s Mike Jones.

Alexander was hampered by injuries in 2017 but is still the best cover cornerback in this year’s draft class according to most experts. Coach Jon Gruden and general manager Reggie McKenzie have already aggressively begun overhauling the team’s secondary, cutting CB Sean Smith and CB David Amerson and adding a top-20 CB in Rashaan Melvin as well as the veteran CB Leon Hall in free agency.

Adding a player like Alexander with the return to health of 2017’s first-round selection, CB Gareon Conley, would go a long way to curing what ailed the unit one year ago. Here is Draft Wire’s 2018 NFL scouting profile on Alexander.
