I once observed a boss that trusted no one until the "proved" themselves over and over again on small jobs; small projects. Finally, after many years, they would get a big project and from that point on, they could do no wrong (in this bosses opinion).
I believe the BC is a lot like that. You have to show him in practice over and over again. Then, you might get to play, but only when a "regular" is injured, too tired or the game is very, very safely in the Win column.
During spring and fall practice we kept hearing about Helo, Prince, Blue and others. Coaches praised their speed, hitting ability, etc. I believe the only way these promising people will ever see any meaningful play time is if BC is FORCED to bring them in. The only reason Quintin got some playing time is because Cody was injured. If Glenn was healthy, we would never or only rarely see Quintin this year.
Thats just the way BC is.
