Look, for a team like PHI, two late, late 1sts aren't really that valuable. They already have too many young players to look at. They also are ready to stop losing as much. They know they aren't a playoff team, but with the number 1 pick, they want to take steps forward.
They, more than anyone, will be willing to "overpay" to marginally improve as long as it's not a major sacrifice. They need vets and stars more than role players and with the odds of late firsts ever panning out let alone becoming rotation players I can totally see them "overpaying". Even if it's not for TP.
Heck, look at what BOS offered last year to try and get Winslow. An unproven and bad offensive player. When teams have too many draft picks and need talent, they are willing to overpay to get what they need IMO.
