Who is the definate #1 CB in the Draft?

From what I have seen, DRC is a better returner and catcher than McKelvin. If someone could really be taught to catch, why are Henderson and Co. still leading the league in drops?

McKelvin had something like 7 kick return TDs, I'm pretty sure he is the better returner.

And it's not like he has brick hands, he can still catch, just not as well as DRC
