Who knows at this point. Last year there were times Miami carried 4 and activated only 3 (most notably the wild-card game). I think Ginn, Bess, Turner, Camarillo - if fully healthy, and Hartline are safe bets to make the roster. One thing that stands out to me is Miami carried 6 OLB's last year, and with the entire corps being boosted with Jason Taylor and Cameron Wake, some of those guys, like Walden last year, will be your special teams players, which might limit the amount of roster space to carry a 6th WR, especially if one of them is a decent special teamer (Hartline - who was also picked based off feedback from the Henne workout tour) which makes it harder for guys like London and Armstrong to stick, unless they really standout come preseason. I'd say London has a better shot over Armstrong, but with Turner in the fold, he's probably one of the last ones to make it if he does. After all, he only tallied 7 catches last year counting the playoff game in which he had 4.
