Assuming Bentil is also signed per reports, combined with the Zeller & Green signings, that puts us at 18 players under contract.
Thomas
Horford
Bradley
Crowder
Johnson
Brown
Jerebko
Olynyk
Smart
Rozier
Zeller
Green
Hunter
Young
Mickey
Jackson
Bentil
Holand
That's 3 too many.
Holland is a free cut (non-guaranteed contract) but the word is both Jackson and Bentil are getting some guaranteed money. Signing them now not only puts pressure on the limited roster slots, but also has the effect of starting the clock on their rookie contract years-of-control.
Unless a trade is in the works, signing Holland and Bentil (instead of stashing them) seems like a very unusual move right now.
So it seems very much like a trade is brewing, though I suppose it may not happen for a little while.
Newly signed rooks can't be traded for 30 days. Once signed, FAs like Green can't be traded until December.
Of course, if none of those players are actually part of the trade, then none of those delays would matter.
Has Jaylen Brown been officially signed yet? If not ... hmmm.
