A few signs point that way.
1. Crit Pro's RBR headers are stamped by Google groups as originating in
the Pacific time zone. Saunders (http://eriksaunders.com) lives and
trains in Twentynine Palms, Calif., also in the Pacific time zone.
2. Crit Pro refers to www.stolenunderground.com in his anti-doping posts.
Stolenunderground is the first link on Saunders' web page on his "Links"
page.
3. Language and style. Saunders' web page makes heavy use of "three-dot"
sentence structure with few capital letters. Crit Pro rarely uses 3-dot
but often drops the capital letters. The writing style (direct, staccato,
blunt with some profanity) of Crit Pro and Saunders are fairly similar.
4. Crit Pro claimed to be in Downers Grove for the crit championship.
Saunders raced there.
5. Crit Pro claimed to be at T-Mobile Int'l today, but his time stamp for
his newsgroup post the same day at 5 pm is too soon for Saunders to make
it back to 29 Palms, only 2.5 hours after the race concluded. Crit Pro
claimed to DNF. Interestingly, Saunders' name is not in the T-Mobile race
results, not even as a DNF; this would suggest that Saunders never left
SoCal. Or, he used a laptop and T-Mobile's results list wrongly omitted
Saunders' DNF.
6. Most riders don't publish web sites the way Saunders does. There are
some, yes, but Saunders' is unique with its in your face style. The web
page suggests a desire by Saunders to get his persona "out there" for all
to read. Just like Crit Pro.
