First-rounder Jakub Vrana, drafted No. 13 overall last month, has signed a three-year, entry-level deal with the Washington Capitals. His NHL cap hit would be $832,500 for all three seasons and $70,000 per season in the AHL, according to the Capitals. The Czech Republic native joins his fellow countryman Vitek Vanecek, a goalie and second-round pick by the Capitals last month, in signing their contracts on Tuesday. Vrana dazzled during development camp last week at the team’s practice facility in Ballston, where he had been living since coming down from Philadelphia following the draft. In particular, a whirling shootout goal on the first day of intrasquad scrimmages turned more than a few heads, including the netminder he was opposing.
