Why do we never see any one develop beyond what they always were? For example: Note: I’m not people saying people develop into being great at everything. Everyone has strengths and weaknesses, but I do believe everyone can be coached to being more well-rounded.

1. Brian Burns in run defense. It’s been a few years, and he is still just awful. Good speed rusher but hasn’t developed at all in anything else
2. Jeremy Chinn pass coverage. Great run defender. Still can’t cover a bed still
3. Tremble, still a great blocker, but after years , it still catches a ball here and there
4. Terrence Marshall. Just apparently completely useless
5. Icky can’t pass block after almost 2 years
6. Zavala doesn’t even look like he belongs in the league

My point is we never ever make anyone better they just kinda are what they are when they get here and never get better.
