4. Thatcher Demko, Vancouver Canucks:The 24-year-old earned a greater role after starter Jacob Markstrom had a procedure for a lower-body injury and will be reassessed in one week. Demko is 11-8-2 with a 3.08 GAA and .903 save percentage in 23 games (21 starts). He won three straight games with a 2.95 GAA and .905 save percentage from Dec. 3-29.
"He's going to be expected to play more but has played exceptionally well from the start this year," Weekes said.
5. Igor Shesterkin, New York Rangers:The 24-year-old has the lowest GAA (2.23) and highest save percentage (.940) among rookie goalies having played at least 10 games. Shesterkin was involved in a car accident Feb. 23 and is out indefinitely with a nondisplaced rib fracture. He will be reassessed in approximately one week.
"The only reason I have him this low (No. 5) is because of games played (10), but he's done everything that he did in the Kontinental Hockey League, the American Hockey League so far in the NHL this season," Weekes said.
