Monk and Fox can play together the problem is and always will be Derozan. You can’t have a third ball dominant player that guy should be a wing defender even a guy like Cam Johnson would work. That’s enough defense to work with an elite offense but y’all love the 35 year old iso scorer
If you add a guy like Herb Jones at SF, I’m sure the defense would be fine if you start Fox, Monk, Jones, Murray, and Sabonis. But when you survey the NBA landscape, how realistic is it that we can add a great/elite defender at SF? I don’t think it’s very likely.
You know what would be a much easier way to build a balanced roster and improve our defense? Start the elite defender we already have at SG and have him close out games for us. Voila! Our defense is all of a sudden much better.
As for DeRozan, I don’t like him better than Monk. In a vacuum, I’d rather have Monk than DeRozan, but the reason I suggested trading Monk is largely due to who else we have on the roster (Ellis and Carter).
Let’s try explaining this a different way to see if it resonates…let’s say the only guards we had on our roster were Fox, Monk, McLaughlin, and C. Jones, and let’s say we had DeRozan, Murray, Herb Jones, and Jarace Walker at forward. You best believe in this scenario, I’d be looking to move DeRozan knowing he’s blocking an elite defender from starting (Herb Jones) while also knowing we have another young forward who projects as a terrific fit with our core (Jarace Walker). As you can probably tell, I’m equating Keon Ellis to Herb Jones and Devin Carter to Jarace Walker to illustrate my point that it’s more about our roster construction and less about the specific player.
As for your proposed solution of adding Cam Johnson and starting Fox, Monk, Johnson, Murray, and Sabonis, I think you’re either 1) significantly overrating Cam Johnson’s defense or 2) significantly underrating Ellis’ defense. Considering you’re a Kings fan and have seen Ellis play plenty of times, I’d venture to guess it’s #1.
Johnson is an average defender (above average at best). He’s nowhere near the defensive impact of guys like Keon Ellis, Herb Jones, Alex Caruso, Jalen Suggs, the Thompson twins, etc. Johnson is ideally the guy you have defend the weaker offensive option between SF and PF but also don’t feel like he’s some major defensive liability out there.
In the scenario I posted above, it not only resulted in us being able to start (and close) games with an elite defensive game changer on the floor (Ellis) but it also resulted in another marginal defensive upgrade by replacing DeRozan with Johnson in the starting unit.
