Here is the best team I think I could build with undrafted players:
Starting Lineup: Damian Lillard G ($42,492,492.00), Luguentz Dort G/F ($15,277,778.00), Kevin Huerter G/F ($14,508,929.00), Michael Porter Jr. F ($30,913,750.00), Wendell Carter C ($14,150,000.00)
Bench Rotation: Patty Mills PG ($6,479,000.00), Larry Nance Jr F/C ($9,672,727.00), Thomas Bryant C ($1,968,175.00), Ziaire Williams G/F ($4,591,680.00)
Occasional Rotation: Keita Bates-Diop F ($1,878,720.00), Keon Johnson G ($2,681,040.00)
Deep Bench: Brandon Boston Jr. G/F ($1,563,518.00), Vit Krejci G/F ($1,563,518.00), Kennedy Chandler PG ($1,200,000.00), Josh Minott SF? ($1,017,781.00)
Total Salary: $149,959,108
Beyond the high salary guys, we did a good job of combing through the real difference makers and the rotation level small forwards. Other than the Deep bench guys and Michael Porter Jr., I think all of these guys should have been drafted. Theory of the team - as mentioned, there is a little less talent available than our teams, but there was a lot of shooting left. Dame and MPJ are two of the better 5-10 shooters in the NBA, Huerter isn't that level but he's a strong plus shooter at either SG or SF, Dort isn't a great shooter but shoots and knocks down enough to have a small bit of gravity, and Carter likes to think he's a shooter. On the bench, Mills is a plus-plus shooter, Nance is more perimeter oriented for a big and can kind of stretch it out, and Williams was drafted in part due to his shooting (he might be about the biggest surprise non-drafted player to me).
Defensively, it's going to be rocky. Carter is a good defensive center, Dort is going to get the tough matchups, Huerter can occasionally hold his own, but Lillard and MPJ suck. On the bench, Mills is worthless, Nance is nice (and would be the sixth man coming in for MPJ), Williams has lots of potential, Bryant is a real honest to goodness center (when healthy), and Bates-Diop can hold his own at SF/PF.
Overall, this team is betting on the continued health of Lillard and MPJ, who have both looked very good, the development of Wendell Carter and Ziare Williams, and one of those cheap guys making it into the rotation (Bates-Diop is playing real minutes for the Spurs, the Blazers are really high on Keon Johnson, Boston was looking alright in LA last year).
Undrafted Honorable Mentions:
Zach LaVine $37,096,500.00 - He's a top 25 type player but his salary was just too high
Deandre Ayton $30,913,750.00 - His salary was just too high, but probably a top 10 center
Chris Paul $28,400,000.00 - Kind of surprised somebody didn't draft him. His salary is high but doable. Ultimately, I think his slow start turned people off.
Malcolm Brogdon $22,600,000.00 - He's looked good in Boston but $23M for 6th man or definite 5th starter is a lot.
Spencer Dinwiddie $20,171,427.00 - If he continues to play this well, he deserved to get drafted.
Aaron Gordon $19,690,909.00 - Top flight defender that can do a lot of things, except shoot. I still think he was draftable with that weakness at his salary.
Eric Gordon $19,568,360.00 - I was really torn between him and Hield. Gordon is a good, switchable defender, and can shoot from way deep which helps spacing.
Clint Capela $18,706,896.00 - Ultimately, I understand why he wasn't drafted, but he's a good PnR center that can really defend.
Harrison Barnes $18,352,273.00 - A little pricey for what he brings, but he's a good defender, hits threes, and all the sudden, gets a stupid amount of FTs.
Jusuf Nurkic $15,625,000.00 - Other than Ayton, the best C on the board but with condensed rosters, probably not a great fit playing drop coverage against everybody.
Gary Harris $13,000,000.00 - If he was healthy, he would have been picked. If he is back by the end of this calendar year, he should have been picked.
Patrick Beverley $13,000,000.00 - He's looked bad so far this year but not many good defending PGs that can hit a jumper.
Josh Hart $12,960,000.00 - Surprised he didn't get picked as he is a good shooter, reasonable defender (especially at SG), and a decent secondary playmaker.
PJ Tucker $10,490,000.00 - Another guy that should have been drafted, and I suspect would if we did the draft all over again.
Lonnie Walker $6,479,000.00 - He's probably been the Lakers 3rd best player but he's not really a shooter. He was worth a flyer for somebody.
Danuel House $4,105,000.00 - Not playing many minutes and hasn't been that impressive, but he was cheap and can both shoot and defend.
David Roddy $2,588,640.00 - Homer pick (he went to my alma mater) - He's been playing real rotation minutes for a good team. Would have been worth a cheap flyer.
