If Covington is available for Clarkson somehow, that’s a trade I’d do. Both players are not exactly peaking in terms of value right now.
The way I see it, we’re always going to have 2-3 easy targets on defense. It would be more effective to address that issue with a guy who is better at helping, rotating, covering space ect than someone who has a better chance at staying in front of one guy.
If you have a great on ball defender, it’s not useful if the other team gets the switch and chances are that great on ball defender is (take your choice of anyone in the league) is going to need to rely on his team against the very best players.
