I agree with most of what you said until you began your absurd commentary about Henrik and Daniel Sedin. Cut their losses? One of the twins was in the top fifty point production of the entire league last season and both put up above average numbers for a second line (on a team that runs its second and third lines equally).
Do you really expect a pair of 23 year olds to play on a team's top line that also has Markus Naslund, Brendan Morrison, and Todd Bertuzzi, who most will agree is one of the top five lines in hockey.
Furthermore, 1999 was a poor draft year, particularly the first round. The twins were consensus top picks, and only a few players from the first round have performed better than them (Martin Havlat is the only one you can clearly argue...Stefan, Connolly, Saprykin, Jillson, Tanabe, Jackman, and Boynton have all played well, but not bounds ahead of the twins, if ahead at all, and I'd argue at least half of them haven't).
The twins have established themselves as strong second-line players. They have had no opportunity to claim a top line role because of who their teammates are. They may not have filled the lofty expectations that come with top three picks, but they have proven themselves as above average second line players who continue to improve their all around play every season they have played. They are far from busts or major disappointments considering their situations.
