I could see it. If the youngn's are as good as we hope and they're one difference-maker away from being competitive... What's the alternative? Tank for a hope at the risk of sucking for a decade and maybe wasting Lenny/Hutson/Cristall's cheap years? If they have cap room, which they should post-Ovie/Carly, why not pay up for the last big piece?
I'm not saying that's how it will go, but I can envision the path.
They clearly do not want to go full rebuild unless they have no other choice. They totally lucked into a top-10 all time great, but it's SO risky. You more likely end up as the next Buffalo/Chicago/San Jose than as Pittsburgh circa 2006.
I don't know, man. If you're unexpectedly this close to contention with Ovie in his final years, you have to do whatever it takes to maximize that. I'm not arguing for selling the farm, but if there's an upgrade to be made, you make it and seize the moment.
