A lot of trades are being published here and I decided to do one too.
Cardinals give: 15th (1st rnd) , 79th (3rd rnd) , 2019 4th round
Value : 1050 + 195 + 70 (estimated) = 1315
Raiders give: 10th (1st rnd) , 185th (6th rnd)
Value: 1300 + 17,5 = 1317,5
We know that Arizona needs a future QB because Bradford is not trustable and they might have to trade up to get one because Miami or NY Giants (trade with Bills in my mock) are picking ahead of them.Oakland has a horrible defense and an underperfoming OL so they need as many picks as possible.
Cardinals give some important picks but that should not hurt their draft as they have a compensatory pick on the third round. Raiders have a lot of positions to upgrade so moving down some picks will not make much difference if they are adding more talent on day 2, also they have FIVE sixth round picks.
How the pick will be used:
Arizona - Lamar Jackson - QB - Louisville
In my mock Darnold,Allen,Rosen and Mayfield will be taken on the first 4 picks, so a lot of talented players will drop and the teams from 5th to 8th/9th might not want to trade their pick ,because of the talent available. Last year Mahomes was more of a late first round prospect like Jackson but was taken much higher because of the importance of a QB and the number of teams that need one and this year could be similar. Jackson has won the Heisman but is not ready to be a starter, but his potential and physical ability are solid and he could turn into a star. After the success of Deshaun Watson that a lot of people said that was going to be a bust, I trust more in mobile QBs.
Oakland - Denzel Ward - CB - Ohio State and Maurice Hurst/Trenton Thompson - DT or Geron Christian/ Brian O'Neill - OT
You might be surprised that he is available, but the QBs going early made some prospects drop. In my mock Raiders will trade with the Redskins to move up ahead of the Packers and take the best corner of the class. They have 1 second round pick and should use that on a LB and with two third rounders OL and DT are the priorities.
I think that is a win-win move and both teams should fill big needs.
