Errrr... didn't they just traded TT in order to dump Bickell? Even Bowman makes mistakes. Also, I don't think the return for Saad was that great, certainly not a "king's ransom".
CHI has only been able to cram so much scoring talent into their line-up because of that peach of a deal Keith signed (cap circumvention) and the fact that Toews, Kane, Saad, and Seabrook all flourished early in their careers whilst on very, very cheap deals. We don't have that luxury (and neither do many teams) and, when we did, we won the cup with Getzlaf and Perry on cheap ass deals.
I think what you're really frustrated about is that we don't have more young, cheap talent coming through in the form of draftees. Hence, the desire for depth scoring to replace that missing talent. I can understand that frustration. Etem was a bust, Holland didn't meet his projections, Palms didn't fit here/moved too early, etc. However, I really think we're turning a corner on that front. Cam was a good pick up, Rakell was a great 30th OA pick, Gibson is slowly getting there, Lindholm has been a revelation as was Andersen, Theodore, Ritchie, Montour, we're getting somewhere. It's just unfortunate that those guys will probably only be ready by the time Getzlaf and Perry have declined. Not really sure what BM can do on that front other then keep drafting for when Getzlaf and Perry are gone. I don't think overspending on depth scoring is the solution though, especially if it puts re-signing core players i.e. Lindholm and Rakell, at risk.
I'm 100% confident that BM feels the same way, but moving the Stoners/Bieksas of this world isn't easy and may even cost us. If BM brings in a high-end LW, I have no doubts about whether or not he'd keep them. I agree that BM lets go of depth forwards too easily, but he tends to think highly of core guys.
