We thought adding someone like Conley would do wonders for our offense. It turns out that it wasn't all that necessary. Harris is fine, it's just that you'd be getting him for his offense, which, again, doesn't seem all that necessary, and we already have Conley, Clarkson, and Bojan who are good offensive players but marginal defenders. Harris is just perpetuating what we have in spades. OPJ would be a guy who can play in crunch time and brings as much to the offensive side with his shooting ability, but brings a lot of very important stuff down the stretch with defense.
Currently our closing lineups don't have people bringing strength on both sides of the ball. Royce can be a good defender, but he's not bringing you anything on the offensive side (and I'd say OPJ is a better defender). Bojan brings great offense and clutchness, but no defense. Donovan brings great offense but average defense. Gobert brings what Gobert brings. We need a guy who can be inserted into the closing lineup for both ends, and that's OPJ. Putting Harris in a closing lineup does absolutely nothing to bolster our weaknesses, and brings nothing to the table offensively that we don't already have.
OPJ brings balance.
