Significant minutes are not to be had. Even without injury. Kawhi will play 30+, leaving 18 or less per game to be divided up among Green, Belli, Manu, Daye, Anderson, and maybe even Boris in wierd/extreme situations. There are a lot of options at SF. A lot of people say RC didn't address the issue, but the last two players acquired were forwards. So, he addressed it. He just didn't address it to some of fans' liking. In the case of injury to Kawhi, there is no standout defensive stalwart in that group, maybe, but if any team loses any key piece, that is usually the case. Rarely is an equal replacement available. Kawhi and max contract are being discussed for a reason. Marion nor Aminu step in to fill his role if he goes down with injury, and if he's healthy, there are precious few minutes to be divided up amongst the others mentioned, much less another forward. It just isn't a GLARING need.
We also have LJC and Bertans waiting in the wings that can play at the small forward position, so unless Marion or Aminu want to sign one year deals, RC may not be interested based upon desiring to bring over foreign prospects next year.
If Baynes doesn't come back, or if Ayres is cut (I don't think he will be), I would much rather see a shooter, slasher, creator at the 1 (only temporarily for Patty), 1/2, or a Hanga type 3/2, maybe. At least for half the season Patty and possibly Manu, will be unavailable. Tony is often injured, as well. We are much thinner on offense at the 1/2 right now.
