It will be a battle between Carter and Collins for the first to 50m, likely won by Carter. Gatlin will also be in there by 50m, and may well go under 10 depending on the conditions.
Atkins is also running, but to me it looks like he runs like a fast old man--very fast, of course, but I'm not expecting big things from him, yet.
Rodgers is also running, of course. If there is a meet within a thousand miles, Rodgers will run it.
And he will do well.
Of course I'd love to see Collins win. This is a fun line-up, because there will be a bunch of guys of similar ability competing--Rodgers, Carter, and probably Gatlin are in the same ballpark, with Collins possibly not far behind. We haven't seen Collins for a while this year, and he is likely to improve on his earlier time.
While these guys are traveling, Gay and Bolt seem to be playing it smart by staying close to home, at least in the same time zone. I don't expect any killer times from these guys in Doha, unless they screw up the timing for Gatlin's benefit. Somebody told me they love him in Doha.
I'm calling Gatlin for the win in 9.97 basic, which would be a smoking time IMO
