Porter, the third overall pick by Washington in 2013, emerged as the team’s third option on offense in his fourth season behind John Wall and Bradley Beal. The 24-year-old wing started 80 games and set career highs in scoring (13.4 points per game), rebounds (6.4) and steals (1.5) while shooting 51.6 percent from the field and 43.4 percent from three-point range in 2016-17.

In fact, according to ESPN’s Real Plus-Minus, a player’s estimated on-court impact on team performance, measured in net point differential per 100 offensive and defensive possessions, adjusted for teammates and opponents, Porter (plus-3.6, 24th highest in the NBA last season) was more valuable than both Wall (plus-2.26) and Beal (plus-2.25) last season. Porter also was the most efficient scorer in the NBA among 115 players with at least 800 possessions, penetrating defenses in transition and as a spot-up shooter.

As a result, Porter was worth 10.5 wins above replacement, boosting his regular season contribution to 16.5 wins above replacement over the past two seasons. There are only 12 other active shooting guards and small forwards with that many or more wins above replacement in their third and fourth years in the NBA, and it’s a list that includes LeBron James, Kevin Durant, Kawhi Leonard, Jimmy Butler and Giannis Antetokounmpo.

That means — brace yourself, Dan Steinberg — Porter might be undervalued in the current market.

Based on what teams must pay replacement-level players (approximately $1.2 million per player), the amount a team spends above and beyond those minimum contracts for a 12-man roster ($86.5 million), and the number of wins it takes to go from replacement-level to league average (25), each win above replacement costs $3.1 million under the $99 million salary cap. That would value Porter’s 2016-17 production at approximately $32.6 million, or $130.5 million over four years. FiveThirtyEight’s CARMELO projections are even more optimistic, estimating Porter’s five-year value at $181.5 million, which prorates to $145.4 million over four years.

It’s not that far fetched. Porter would need to provide 8.1 wins above replacement each year for the next four years to justify the max offer by the Nets, roughly the equivalent to his average production over the past two seasons. And that’s if the salary cap remains flat — it has risen from $58.7 to $102 million since Porter was drafted and is projected to hit $120 million for the 2020-21 season. In that environment, Porter’s 2016-17 season, the 24th best by wins above replacement, would be worth more than $40 million.
