I can't go along with you on that at all. He was caught with his hand in the cookie jar. He did what he had to do - - apologize. He learned by watching Giambi and Pettite. Giambi was a man about it....Arod simply did what was in his best interest. If a denial was in his best interest, he would have done that.
The only other alternative was to defect, hide, cower, lie, deny and make excuses like a number of others (cough, Bonds and Clemens, cough). A-Rod took the higher road.
