I think you have to factor in playing time.....an audition..
Most players show what they are as soon as they play. Now, their "audition" may not occur in earnest until their 3rd year, but they show once they play. That was the case with Crowell. With Sheppard, he got his audition in year 1. I don't think he's going to suddenly become something he's not in year 3.
It's like the kid who played Anakin Skywalker in Star Wars III. Bad actor, right? I'm pretty sure he's bad in every thing else he's in. I don't need to see it. Same with Shep.
That's my unsolicited view anyways
