CB was a big need, and this guy gives them some flexibility. They can use him as the slot corner, or take MB or HaHa out and use him in the Woodson role (might be a bit much to ask in his first year). Combine with Clay moving in and out and you have a recipe for confusing the offense. Or a recipe for confusing themselves when there are 'communications breakdowns'.
I won't say I love this pick, but I certainly don't hate it.
