Donovan McNabb had his best practice on Monday since being traded to the Redskins. ?I think it was (his best practice)," said Mike Shanahan. "He had a good day today. And you can just tell he?s feeling more comfortable with the system and more comfortable with the reads. It just takes some time, like learning a new language. I don?t care who you are ? if you learn a new language, it takes some time before it comes out automatically and you can think. I think he?ll feel much more comfortable with it in the next few weeks and get ready for our first game."
