With Ottawa's two second-round picks, the Senators selected two Swedes: winger Jakob Silfverberg from Brynas Jr. and goaltender Robin Lehner from Frolunda Jr.

Silfverberg is about average sized at 6'1" and 190 lbs, although he's still on contract with Brynas so won't likely come to North America for next season. According to Elite Prospects, he's got some good upside:

Silfverberg is a strong skating two-way forward with good hockey sense. He is a very smart and mature player and is solid both offensively and defensively. Silfverberg has good technical skills and plays with plenty of intensity. His shot is quick, but could be more accurate and he does not really play very physical.

Although Hockey's Future was more reserved in their analysis:

Silfverberg is a strong skating two-way forward with good hockey sense. He is a very smart and mature player and is solid both offensively and defensively. Silfverberg has good technical skills and plays with plenty of intensity. His shot is quick, but could be more accurate and he does not really play very physical. Opinions about Silfverberg's career differ. Some see a potential star player in him, while other see his potential limited to that of a role player. Could be a wild card in the NHL draft and selected much earlier than projected.

As for Lehner, he's a big goaltender at 6'3" and 220 lbs, but it sounds like rebound control may be an issue--shadows of Martin Gerber, although Lehner's young enough to get the help he needs. Not sure what his contract situation is, but the B-Sens could sure use some help in nets. According to Elite Prospects, his size is advantageous:

A butterfly goalie with excellent size and good overall skills. Uses his big frame to his advantage and challenges the shooters, although perhaps not with the desired consistency. Rebound control is somewhat suspicious, but overall mobility quite impressive for a big guy. Moves pretty well side to side and is tough to beat down low.

Which is the exact write-up he's got on Hockey's Future, although HF also has a huge article on Lehner's performance at the U18 tournament, which is worthwhile to check out.
