I still think that Laney & Copper are much better examples (especially compared to Sabally). I know that ppg is only one stat, but I don't want to further convolute (and none of the below are point guards or posts with huge apg, rpg, or bpg):
Plum's 1st 4 yrs: 8.5, 9.5, 8.6, & 14.8;
Young: 6.6, 11.0, 12.2, 15.9;
Sabally (only 3 prior to this yr): 13.9, 11.9, 11.3;
Laney: 2.9, 1.0, 2.7, 5.6;
Copper: 6.2, 6.7, 7.1, 6.7 (relatively no upward arc)
Laney (yrs 5 through 7): 17.2, 16.8, 11.2 (injured)
Copper (yrs 5 through 7): 14.9, 14.4, 15.7
Young & Plum were #1 overall picks & Sabally was #2, so they had a longer leash as well.
So, I guess I'm doing a horrible job of asking my question and tying it in to the current batch of newbies that aren't setting the world on fire out of the gate. I don't think there was ever any real consideration of waiving Plum, Young, or Sabally; but how did the 2 Scarlet Knights stay in the WNBA (Laney actually was 5 yrs in averaging no higher than 5.6 ppg due to missing a full year -- yes, she exploded in the wubble, but how did she survive to get there?) and how should that apply to current 1st, 2nd, 3rd year players?
