Unfortunately I do have to echo STMB's sentiments regarding Richard. Instead of an injury setback, I was more leaning to the possibility that he is still under a very heavy training load in comparison to Dix, as he has just looked very flat. We have to remember that even though Dix is already flying, he had/has less to work on than Richard. The issues of speed endurance and general strength were never a concern for Dix. Technical issues is their only mutual problem. Not to mention Dix has to be in peak shape for his trials in 8 weeks time, Richard does not have that concern or has it to a lesser degree.
Richard has Darvis Patton, Nesta Carter, Frater and Bolt for opponents this coming Saturday in Jamaica, so lets see what happens in the first real meet of the season.
