One of the early season storylines during the Trail Blazers’ 3-1 start has been the emergence of a deep and effective bench.

Led by Evan Turner, Ed Davis and Pat Connaughton, the Blazers’ bench has the top offensive rating in the NBA (115.8), the third best net rating, and the third best plus/minus behind Toronto and the LA Clippers.

Never was the bench more on display than during Tuesday’s home opener against New Orleans, when the starters struggled and needed big games from Davis, Turner and rookie Caleb Swanigan to pull out a 103-93 victory.

“Our bench has been huge,’’ starter Maurice Harkless said. “Especially on a night like tonight, when nobody really had it going. Ed, Caleb, and Evan kept us in the game the whole time, whether they were scoring, rebounding, defending. Especially Ed. But this is going to have to be a collective effort. We need everybody.’’

Turner has been the catalyst and could be establishing himself as a Sixth Man of the Year candidate as the league’s top reserve. Through four games Turner is averaging 13.3 points, 4.3 assists and 3.8 rebounds while shooting 46.2 percent from the field and amassing a solid ratio of 17 assists to six turnovers … all while playing solid defense.

“It’s starting with ET; he’s leading the show and playing well,’’ Davis said.

The same, of course, could be said of Davis, who was probably the Most Valuable Player of Tuesday’s win over the Pelicans with his 12 points and 10 rebounds in 21 minutes.

It has been a resurgent return from shoulder surgery for Davis, whose 9.3 rebounds is second behind Miami’s Kelly Olynyk among bench players, and his play is backing up a vow he made to Lillard last spring.
