I don't mind a QB dumping a short pass to a RB behind the line of scrimmage. I just don't understand the issue. So this just adds up to more times a QB has to just throw it away. Yeah, those plays are exciting.
If Kwity Paye is there at 21, IMHO, it's a no brainer. You grab him and know that not only did you fill a position of need but, you grabbed the highest rated player on the board. Meaning: You stayed true to your board and took BPA. Paye is a top 10 player in the draft and his passion to succeed based on his journey and overcoming is what will make him an All-Pro.
If Paye isn't there, I agree with @MikeCurtis, you take the best tackle on the board, unless there are none left with first round grades. In that event, you stay true and take PBA.
