Great fit from a length standpoint. Jackson has long arms and Seattle under this regime has never drafted a cornerback with sub-32 inch arms.
However, they have also not drafted a cornerback in the early rounds, let alone the first round.
The Seahawk drafting tendencies under Carroll and Schneider are very clear cut. They have many tendencies they don't deviate from, which is what allows the Seahawk draft bloggers like Rob Staton to isolate the likely targets with great accuracy. This year the spotlight on his blog for more than six months was running back, yet somehow outsiders were surprised when Seattle drafted a running back in the first round.
The only surprise there was Staton preferred Ronald Jones of USC above Rashaad Penny of San Diego State. I think he was correct there, because Ronald Jones was among the three backs who fit Kent Hullamania's running back criteria of quickness and yards after contact. The other two were Darius Guice and Roc Thomas:
