Patterns emerged along the way, as the Sabres opted to select players who they view as late bloomers with high long-term potential.
"It's a huge balance, taking a player who can play in two years versus taking a player who's going to be even better in seven years," Jankowski said. "That's a very different way of looking at things. From my standpoint, it's about keeping our guys focused on the player, what he's going to be at the height of his career."
Here's what Jankowski and general manager Jason Botterill had to say about each of the team's selections, including first-round picks Dylan Cozens and Ryan Johnson.

Botterill spoke about Cozens' positive qualities after the first round, from the mental maturity he developed after moving away from home at age 14 to the rare blend of speed and size he offers at the center position.
Jankowski said he sees a player who will add to the organization's depth down the middle, joining Jack Eichel and Casey Mittelstadt.
"He's going to be a good centerman in the NHL," Jankowski said. "This organization now, with Jack and Casey and Dylan, it gives us great options. So, we think that he's a guy who's going to be able to produce some offense while playing a well-rounded, 200-foot game with good size.
"He still has the frame to fill out, still a little bit immature physically. Which is great, it shows there's a little bit of upside there and it gives us good depth at the center position."
Ryan Johnson, D - Sioux Falls (USHL)

After using five of their six picks in last year's draft to bolster their defensive depth, Johnson was Buffalo's only selection on defense in this year's class. The son of former NHL forward Craig Johnson was the USHL Rookie of the Year and a Clark Cup champion last season with Sioux Falls.
Johnson described himself as a puck-moving defenseman with a high work ethic. Jankowski used the term "new-age" to describe the blueliner, with a blend of skating, puck movement and hockey sense and the potential for offense.
"We think that the offensive upside is still being developed in his game," Jankowski said. "He had that as a younger player, didn't have a ton of numbers in the USHL this year but it is a hard league to bring offense as a defenseman. I call him a new-age defenseman.
"He skates extremely well, he moves the puck extremely well, he defends with his brain. ... So, I like the well-roundedness of him. From an offensive standpoint, we think that can still come. But even if it doesn't, we know we've got a new-age defenseman that can move the puck and skate."
Johnson will continue his development with the University of Minnesota next season.
Erik Portillo, G - Frolunda HC J20 (SuperElit)
Botterill said going into the draft that he'd like to add to the organization's goaltending depth. In Portillo, the Sabres added a long-term project who previously played in the Frolunda organization (Rasmus Dahlin's former team) and has a North American development plan in place.
