The big factor is that his oRtg in the playoffs was miserably low with a high dRtg. Yes, everyone's dRtg went up, defending against great offenses. But his oRtg was 21 (!!!) points separated from his dRtg. Ingles, by the same regard, was only one point (110 oRtg, 111 dRtg), and was regarded as playing poorly for chunks of these playoffs. Exum was metrically horrible offensively and defensively, and it isn't an oddity that he was a net negative out there (By a lot BTW, he was a -5.8 BPM --> really really bad). Exum was team worst in oRtg AND dRtg in the playoffs. He was the only regular minute-getter on the team that had a negative win-share rate in the playoffs (Udoh and Stockton the only others).
People forget that he was turning the ball over at a historic rate in the playoffs for a minute (almost one third of his possessions through one long stretch), and even after somewhat righting the ship in that regard, finished the playoffs with a > 24% Turnover Rate (!!!) to go along with his 0.66 A:TO ratio (again, really bad).
Look, i get it that he could someday become worthy of the $11M contract. Can we stop pretending like he's shown enough to earn it up to this point? Hes a career 20 mins-per-night , 40 games-played, 6p/2r/2a player now making >10% of the salary cap. Jazz are taking a huge leap of faith IMO, especially when it appears they outbid themselves to overpay him. Teams usually pay the RFA contract based on past results mixed with potential. This contract is still 99% potential.
