In any case, talk of dodging is just childish nonsense entertained on these boards, and both riders should try to maximise their own results as best they see fit.
Your sentence is self-contradictory, since riders have been dodging other riders since the beginning of racing, mainly for the purpose of maximizing their own results. It doesn't mean they are afraid, or weak, or non-competitive, it just means that maximizing one's own results necessarily involves consideration for who the competition will be. I bet the announcement that Contador is NOT racing the Giro will mean some riders are MORE likely to race it now, since the competition is slightly weaker, and their own chances for victory just a little bit greater.
Riders also dodge entire races: Wiggins said he is riding the Giro because it is not as hard as it was in the past, for example, and Contador is dodging the Giro this year because racing it would be too disruptive to achieving his main goal, the TdF. Without a doubt Contador also noted that Wiggins was in the Giro, and factored this into his decision.
Far from being "nonsense" confined to these boards, all of this is a necessary part of being a professional bike racer and running a professional cycling team trying to get the best results possible.
