The NFL on technology.....

In my Information Week daily update yesterday, I read an interesting article on the NFL and technology.  They state that technology in the game has come along way in the last several decades in the game.  I totally agree with them on this and it shows now.  Years ago in order to communicate with the quarter back you would have to use hand signals.  In the mid 70 and early 80's wireless radios were used in the quarterbacks helmet in order to communicate with the quarterback and this was a big step in technology for the teams.  Now with todays technology Blue tooth technology has stepped in and the wireless communication between the sidelines and offensive and defensive players is even better.  Things have come a long way since the days of hand signals.
