PG is the most demanding position with the direction the game has taken; there won't be any hiding for Bron if he's guarding PGs on the regular (which he probably won't be). And I mean, the only real "glaring weaknesses" he has in his game is through age and wear and tear, not anything fundamentally or skill-wise.
The last thing the Lakers want to do is have him initiating the offense on every possession and navigating through screens to stay on PGs.
The Warriors won more games than every team in history over one season, two seasons, three seasons, four seasons and five season periods, off the back of Steph having arguably the most offensive impact and Draymond having arguably the most defensive impact we've witnessed - as long as those two are playing at a similar level, it's hard to see the Warriors dropping all the way off to where four teams in the West are winning at a greater rate.
In a regular season context, the departure of Durant will only be beneficial to their offense, as now it can go back to functioning completely around Steph, and not trying to force a fit with an ISO-based player which would often be in conflict with the nature of it. And although the loss of Klay puts a cap on their wins-ceiling, having Dlo as a replacement will layer their ball creation, player and ball movement (as we know, passing/creating aren't Klay's strongest attributes), which will only add another dimension to their offense. I wouldn't be surprised if it functions at a higher level than it has been over the last three seasons.
Not to mention, the addition of WCS is probably the best-fit 5 they've had in the Kerr era, and their bench is the strongest its been since 2016.
