Detroit had a riduculously bad offseason. Grant 3/60mil and Plumlee 3/25mil. Then they let Christian Wood walk for 3/41mil. You're willing to pay +7/year for 30y old career backup level Plumlee, but not to a very promising, awesome advanced metrics Wood for +13mil/year that also fits so much better to your team? Considering their lineup:
Rose/Haynes
Svi/Wright
Grant
Blake
Plumlee
Good luck to their rookie pg. Absolutely horrible spacing, one complete non shooting center playing with Grant thats below average shooter that needs spacing to be a play finisher and Rose as a below average shooter. Tons of money/flexibility spent and for what? Both of those free agent signings were very bad. Grant is a big overpay to play in a situation that isnt best for him. Those Plumlee type deals are almost always horrible because centers like plumlee can be found for close to minimum deals every single year. Also Doumbouya needs minutes at the 4.
So, unless they play Blake, Grant, Bey/Doumbouya frontcourt a lot, they will be horrible offensively. That would also make the Plumlee signing even more horrible so if I was a Pistons fan I would be furiously questioning these moves.
