Video: Cardinals' Campbell on Kolb trade

The Kevin Kolb trade between Philadelphia and Arizona made both teams better.

The Eagles weren't using Kolb much. They needed another cornerback to navigate a schedule rotation that pits Philadelphia against an AFC East division featuring Tom Brady and an expanding New England Patriots receiving corps. The division also features receivers Santonio Holmes, Steve Johnson and Brandon Marshall.

Meanwhile, the Cardinals needed Kolb to stabilize their quarterback situation and improve their chances in a division now featuring an ascending quarterback in Sam Bradford.

One of Kolb's new teammates, Calais Campbell, discussed the addition recently on ESPN. Cue the video.
