If you miss your connection, AA will accomodate you and get you on the next flight. Look at it this way - if you miss your connection, chances are you'll have to wait an hour or two for the next flight, and you'll be in the same boat as if you had booked a longer connection time. The upside is that you make the tight connection and get to GRB earlier.

I'd recommend booking the connection.
