Are there any Terry Rozier fans left?

[mmmmm]

His destiny seems to be to get traded and become a bottom-third starting PG.

This.
Reggie Jackson 2.0
below average shooter and starter, good playoff performance vs. SAS (?) and unhappiness with OKC backup role

It's not a good comp. Here's Rozier's 3rd yr vs Jackson's 3rd yr: http://bkref.com/tiny/4B8HL

Rozier is not the finisher Jackson was, but he's as good or better in all other facets of the game.

Just looking at the numbers you posted, Rozier's ppg is lower,his apg is lower, his FG% is lower, his FT% is lower, and their steals and blocks are pretty close to identical. It looks like Rozier is a better 3P shooter and rebounder and that's it.

Jackson had 36 starts that year compared to just 16 for Rozier and played more minutes per game.  That's going to favor him for per-game counting numbers.

If you look just at their splits as starters, then Rozier's counting stats start to look better:  15.6 points, 6.4 reb, 5.1 assists in 33.6 minutes compared to 14.1/3.7/5.1 in 31.2 for Jackson.   And Rozier slightly improved those numbers in the playoffs (16.5/5.3/5.7).

Advanced stats, such as Win Shares, are very much in Rozier's favor.  He posted an excellent .130 WS/48 rate in the regular season and an even better .149 WS/48 rate in the playoffs compared to rates of just .104 and .067, respectively, for Jackson.   Overall, between regular season and playoffs, Rozier was worth 7.8 Win Shares on 2764 minutes compared to Jackson's 5.6 Win Shares on 2808 minutes.
