You're now resorting to strawman arguments after 1st going with arguments based you you claiming to know everything Jerry, Blue and everyone else thinks and feels, and ignoring the fact that it is not uncommon for rookies, especially lower draft picks, to not get their college jersey. Additionally you ignore that rookies, again, especially lower round draft picks, don't automatically get to take a number away from a returning veteran. Hell, they don't even automatically make the team.
So yeah, I quit football after 9th grade and focused on basketball and baseball, but that's irrelevant to anything i have written.
Hell, even if you use high school or college as examples, the freshman or sophomore making varsity for the first time doesn't get to walk in an take the number away from a returning veteran, so your argument fails anyway.
