That Klay game (0 points, 0/10 FG, 0/6 3P in an elimination game) doesn't exactly scream "yea let's give that guy a big contract in the summmer" to me.
Meanwhile D'Angelo Russell had 21 points, 6 assists, a steal and a block on 7/14 FG, 5/11 3P.
Both are free agents in the summer, Russell is 6 years younger... I'm not even like super high on Russell but it seems to me whatever you're thinking about offering Klay (if you are) you should stick an extra 3-5mil a season on it and offer it Russell instead.
