Centro is ANOTHER example of a great college miler regressing (***SO FAR*** anyway) once pro. Monzano, Lukezic, Lomong are just recent examples. Yea, there are others who have improved- but too many were at their best (or near) as collegians. Past examples incl. Gabe, Stember, Lassiter, McMullen. Even Holman, who wasn't faster, made the OG's only as a collegian. You CAN'T just lay low all year and expect to run fast, sharp and with a huge kick. It could happen- but again, look @ the milers I named.
