As far as I can tell, the 'official' announcement hasn't been made, but the story being told all over the wires is that Eric Berry has finalized his contract.  The important numbers:

• Six year contract
• $34 million guaranteed
• $60 million maximum

Arrowhead Pride is going chat-crazy over the news, so feel free to see how they feel about our newest favorite son. 

If you break down the numbers, the maximum yields $10 mil per year on average.  That's $625k per game, or over $100k per minute of clock time.  Assuming he's on the field for half of that (which is a touch high), then he's basically making $200k per minute of playing time.  [Edit: Math error.  That's supposed to be $10k and $20k, respectively.  Yeah, I can divide 600 by 60.  --Hooper]  Naturally, that's not accounting for practice time and all the other details he'll be involved with for the team, but that's still a boatload of money.

And none of us could be any prouder.  If there's any player we felt was mature enough to handle this kind of a pay day, Berry's the one.
