db help

We are similar in that we play tight man as much as possible. We have been very good at making plays on the ball in the air - although I agree it is very hard to do. It is an awkward position for a DB - much different than for the WR for some reason.
We do GO-BALL drill every day in practice. I say go and the player starts sprinting away from me. I throw the ball up and everyone yells "BALL". The player hears the call and turns to find the ball, then high points the ball. I mix up the throws. I think this is the major reason why we have done so well - besides having good athletes.
WE also do dog fight. Two DBs start out side by side backpeddling away from me. I throw a ball up and they try to make a play against each other.
Like I said, I think this is a tough skill that can be improved with practice of any kind where a player has to find the ball and catch it at the highest point.
Hope that helps.
