Brisvegas don't get to buy much of anything with 1356 points. They need way more than that. Ashcroft would need to be called at pick four and then Brisvegas would need to also add their couple of late picks to the points and barely scrape in to get him. Straight into deficit on their next years draft first pick to match anything later to get their academy kid Marshall.
They do need more than that, but they can't just snap their fingers and expect it to all come from 1 trade.
From my calcs, if Ashcroft goes at 2 and Marshall at 25, they will need something like 2573 points and they currently have either 1228 (if they win the GF) or 1281 (if they lose it). They need to generate around about 1300 points and hope we don't bid on Ashcroft with 1.
Thats significant value for them if we don't bid. Ie. if we were a risk to bid at 1, they would need 2959 points, so us giving them a pinky promise that we don't bid is worth a lot to them.
In that trade suggested above 39, 41, 47 and 57, they would gain about 330 points (assuming they lose the GF) PLUS "gain" 386 points that they wouldn't need to find if we were no longer a risk at Pick 1. No-one else can provide them value like that.
Would still leave them about 1000 points away, they might be able to get some of that with a Robertson trade (lets say he goes to the Eagles for a trade around 400 points - it would likely be a convoluted one), then they are around 600 points away. I still can't see them being able to get the 2 of them without trading picks from next year, whether thats a F2 or a F1 I'm not sure, possibly depends if they manage to generate extra value out of their picks, but if we got something like 6 and 26 from the Suns for Rioli, I'd be happy to trade 26 to the Lions for their F1 with our F3 going back to them.
They won't do it in 1 deal (so not sure why you are banging on about that they need to, they just need to generate value from trading their 1st pick and they will) but there is a clear path, but they would absolutely need to trade picks from next year and with the drop in the DVI for next year, I can't see them finding say 600 points without giving up their 1st for next year. It would be a brave club to think their F2 won't be in the mid to high 30's. 36 is worth only 317 next year compared to 502 this year.
