I'd really like to see Koufos moved in the offseason for a pick so we can open up minutes for Cauley-Stein & Papagiannis at C next year.
The 2018 draft class has many talented big men. I think we'll need Labissiere, Cauley-Stein, & Papagiannis to log as many minutes as they can next year to give us a good idea of who we should keep long term and potentially increase the value of these young guys in trades. For instance, if all three players look promising next year and we're in a position to draft a big like Ayton in 2018, perhaps we're using Papagiannis or Cauley-Stein as a trade chip to upgrade the perimeter. Now I'm not saying we would have to trade one of them, but moving Koufos for a pick should 1) make us a worse team (better pick next year), 2) allow Labissiere, Cauley-Stein, & Papagainnis more time to develop in-game, 3) give us a better idea of what we actually have in these young men and who fits with our core going forward, 4) potentially up the trade value of these 3 guys if they continue to progress/play like they have been this season, & 5) give us another young player via the pick we received by moving Koufos.
Like many, I'm expecting us to end up with Smith/Ntilikina & Isaac/Bridges (which I'd be happy with at this point). With our 2nd (and the pick we could get for Koufos), I'd like to take Jawun Evans & Jonathan Motley/Jonathan Jeanne/Josh Hart/Dillon Brooks. That would be a good haul from this draft.
In FA, I'd let Afflalo & McLemore go and sign Isaiah Cousins to a 3 year deal and Lawson to a 2 year deal with the 2nd year being a team option. Lawson's passing & playmaking ability would be good to have to not only make the lives easier for the young guys he plays with (Hield, Richardson, Isaac, Labissiere, Cauley-Stein, etc.) but to also help mentor and teach the PG position to our young PGs (Ntilikina, Evans, & Cousins).
That would put us at 15 players (Lawson, Ntilikina, Evans, Cousins, Hield, Richardson, Galloway, Isaac, Temple, Gay, Labissiere, Tolliver, Motley, Cauley-Stein, & Papagiannis). If Bogdanovic was wanting to come over, I'd go ahead and waive Galloway to make room for him. Then we'd have this team going into next year:
PG - Lawson / Ntilikina / J. Evans / I. Cousins
SG - Hield / Bogdanovic / Richardson
SF - Isaac / Temple / Gay
PF - Labissiere / Tolliver / Motley
C - Cauley-Stein / Papagiannis
Then after Gay comes back and reestablishes some value, I'd try moving him for a future pick (potentially a 2019 pick to replace the one we will lose) so we can continue with the youth movement. After the 2017-18 season, we'd have these players guaranteed to be back for the 2018-19 season with another 1st round pick & 2nd round pick in the 2018 draft:
PG - Ntilikina / J. Evans / I. Cousins
SG - Hield / Bogdanovic / Richardson
SF - Isaac
PF - Labissiere / Motley
C - Cauley-Stein / Papagiannis
