He should make a switch to Salazar. Everybody always write bad performance/injury on age, body type or something they think is obvious, still you see guys running near to 100% at the age of 39, and you see guys like Solinsky, Ben True,Alan Webb running well with more muscles. I mean look at Jaouad Gharib, won silver in 2008 Olympics, runs 2:05 at almost 40, and he does not have the elite marathon body type. I really hope Solinsky goes after it for at least 5 more years to see what happens, with Salazar.
