I agree with you that he does care (and I guess I shouldn't have said it doesn't matter who is there), but April got a 1st round pick last year in McKelvin, who was one of the more prolific returners in college football. That included 7 TDs on punt returns as well. Every year we bring in or retain quality ST'ers for April's squad, and I don't see that changing anytime soon.
With the combo of McKelvin/Jackson, I still feel that we'd be well above average in the personnel dept., plus we have April's genius when it comes to the blocking schemes. Not saying that I'd want to get rid of Parrish, but if the right offer came along, it should at least be entertained without the fear that our punt return corp would suffer too much.
