Valverde gifted numerous races to his teammates throughout his career, you obviously didn't follow him closely.He gave Spanish Championships to Herrada, Izagirre and Rojas, Klasika Primavera to Visconti. He rode many times in service of his teammates. Heck he even gifted wins to non-teammates, like Szmyd at Mont Ventoux and Luisle (arguably) in Murcia this year. Valverde is one of the most generous riders in terms of riding for teammates in the whole peloton, so I lost you a little bit at this one
As for this particular race (GP Indurain), he would be more than happy if Betancur could've hold on for the win, or if Soler could've broke through on that penultimate climb when Betancur was caught. But the truth was that Verona was stronger than both, so only he could've beat him, as he did.
