Madden question: Drew Brees Smart QB & Accurate Passer

I don't know why I'm finally asking the question, but I noticed that Drew Brees is not only listed as an "Accurate Passer" but also a "Smart QB". However, you only play with him as an Accurate Passer. How can you switch him to Smart QB, or is that even possible. If not, then why do they even have him listed as a Smart QB.

Same thing with Marques Colston... not only is he a "Possession Receiver" but also a "Spectacular Catch Receiver".

I guess my ultimate question is how do you toggle between player weapon keys?
