Vincent Jackson was one of the biggest free-agent signings of the offseason, and the Tampa Bay Buccaneers invested a ton of money in him.
His first big test of the 2012 season will come in Week 3, when he matches up with the new cornerbacks the Dallas Cowboys have assembled.
While Dallas did add Brandon Carr, and he is probably penciled in as the team's No. 1 cornerback, I'm more interested in seeing Jackson line up against rookie Morris Claiborne.
Before the 2012 NFL draft, scouts raved about Claiborne's natural abilities as a corner and his incredible instincts at the position. The Cowboys traded up to No. 6 for the opportunity to select the LSU product, and he has immediately upgraded the team's secondary.
Watching Jackson and Claiborne go at it will give us an idea of where both stand. Jackson may not be a legitimate No. 1 receiver, but if he can abuse Carr and Claiborne, it will go a long way toward answering any questions about his ability.
Meanwhile, if a guy like Claiborne can shut down someone as talented as Jackson, he will prove just how ready he is to step in and make a difference in the NFL immediately.
