Based on the 3 guys I've redshirted without notifying them during recruiting (I say that to say this is an extremely small sample), the guy whose ovr was in the top 5 on the team was upset about it (-8 to WE, I think - but it was still a good decision because he needed the extra developmental year and I would've maybe won 5 games with him instead of the 3 I won without him... 1st year of a rebuild & sim signed 4 bad recruits before I took over. Signed this guy in RS2 that season).
In two other worlds, the players' ovr was around 10th-12th on the team and they were fine with the redshirt.
So my limited experience makes me think where the player's ovr ranks on the team is a big factor in how he takes the (uncommunicated) redshirt decision.
also... I found this post bc I'm thinking about RSing this guy:

Athl, Reb, Blk, Per, St, & Dur are all greens, and Def & Pass are blues. My 7 returning players have higher ovr, so at best he'll be 8th best ovr on the team. I'm wondering if anyone with more experience redshirting has thoughts. With all those greens and a current WE of 56, I think he's going to be a (D2) stud either way. But with his current 28 athl, I think I'd rather have his 4th and 5th seasons with ~maxed athl (and ~maxed everything else) vs have him contribute as my ~8th or so best player this season & have him do something like this in his 4 yrs: OK 8th man, good 6th man, good starter, stud - and I think it's worth risking the WE hit this season.
I may be too generous in projecting him to be a "stud," but I think he'll at least be a strong all-around player who can rebound, defend, score, dribble & pass at a decent-to-good level (poor man's Draymond, maybe?)... but I'm also hoping his athl & per stay green long enough to qualify him by anyone's & everyone's definition of "stud."
