Thunder Dan has more burst than Freeman right now. Freeman was the guy that knew instinctively how to find the hole in the zone, so teams had a hard time protecting themselves from Brooks. He could get deep, but like James Jones, it wasn't so much speed as technique and guile. His speed wasn't bad when he was young, but not top end for WR then. He got heavier later in his career and that speed disappeared. He never forgot how to get open underneath though.
Be careful Dan, pneumonia is tricky to treat. It doesn't kill the olds outright (though it can) so much as it leads to lots of complications and repeats. Its kind of like a Tramontana tackle, it just hangs on.
Don't be in a hurry to get back to a normal schedule.
