No. 11 is the draft position the Flyers held before Monday night’s lottery and No. 11 is where they’re going to stay. The second-seeded Colorado Avalanche lucked out over the first-seeded Florida Panthers and most likely will go after top-rated prospect Seth Jones, a defenseman from the United States. Philadelphia had only a 1.5 percent chance of jumping up to the No. 1 spot. The Flyers have had the No. 1 overall selection only once (1975) since their inception in 1967. Draft experts believe the Flyers will go after a defenseman if one they fancy is available at the 11th spot when the draft is held at the Prudential Center in Newark, N.J. on June 30. “I would say in my opinion there are at least a half-dozen (prospects who could have an immediate impact),’’ Flyers general manager Paul Holmgren said on Sunday. Holmgren believes he can get the kind of player that can help in the near future.
