To me, TJ Green is on schedule.
The moment "project" is added to a players description, an extra year is added to their development curve.
Swoope for example spent 2 years in development on the P.S.. 3rd year, he makes a positive impression. We didn't see all of his development bumbles and stumbles, we saw the more polished, ready-to-compete version.
Then you have a guy like TJ Green, who's also a "project" player, but because of his draft position and lack of depth at his playing position, gets his number called early, putting all his learning curve bumbles and stumbles on full public display. He has quality measurables, and if he put in the work, and took the coaching, he could show up very well in his 3rd year.
To me, this is the year that determines if the "project" was a success.
