The Sabres think highly of Cliff Pu, so they've wasted little time signing him. Buffalo has signed the forward to a three-year, entry-level contract. Pu is playing his fourth year of junior hockey and will turn pro next season. The contract won't start until then. Pu impressed new Buffalo General Manager Jason Botterill and coach Phil Housley with a solid Prospects Challenge. They rewarded him with two preseason games before sending Pu back to London of the Ontario Hockey League.
