Veteran forward Tyler Johnson is only on a PTO deal, but the former Tampa stalwart believes he can earn a spot with the Bruins.

Riley Tufte certainly looks the part of what the Bruins have been doing this season. At 6-foot-6, 230 pounds, Tufte is an imposing figure on skates. But with the B’s now possessing plenty of size, the 2016 first-round pick (25th overall) of the Dallas Stars has to do more than just look big to stick around on the Boston roster that has plenty of bottom six candidates.

Assuming Jeremy Swayman — who won’t participate in training camp until a new deal is reached — is Boston’s Opening Night starter next month, the Bruins will need to decide whether Joonas Korpisalo or Brandon Bussi will be the backup.
