D'Angelo Russell and Jordan Clarkson seem like the backcourt of the future, but that doesn't necessarily mean that if value comes along or a quality player becomes available, the Lakers should thwart any and all options.
Case in point: per ESPN's Chris Broussard, they're among a few teams that have shown interest in Memphis Grizzlies point guard Mike Conley. According to Broussard, the Lakers, Rockets, Nets and Hornets plan on meeting with Conley at some point in the next week.
Now, with all these rumors linking free agents to the Lakers, it's important to remember this is all part of the season. The Lakers have money, and agents know they can leverage the power the Lakers hold over free agency to help set the market. Look forward to basically any and all available free agents linked to the Lakers in some fashion over the next couple weeks. (I might wind up copy-and-pasting this graf into all these kinds of articles, to be honest)
In terms of basketball sense, I'm a proponent of dual-point-guard lineups. Both Russell and Clarkson have shown an ability to function off the ball (while the former is obviously better with it), so adding Conley to the backcourt wouldn't necessarily throw the rotation out of wack.
Conley also brings the kind of veteran leadership and on-court abilities that resonate with young players. Other veterans who can't play at that kind of level consistently either due to age, ability or injury don't hold the same kind of weight. That's just kind of how that works.
It's impossible to say as of right now how serious the Lakers are about adding the nine-year veteran, but for right now, the signing would make sense, so long as it follows signings at the center and wing positions.
