Let me elaborate a bit further on your statement.
Granted we have plenty of needs esp around the lines. Many of us (me included) believe that Fitz is adequate for a team that is stocking up on talent but is not a superbowl winning QB (accuracy being the prime failing). So, eventually we will need a QB that will help us win the big one. Largely such QBs are not available in FA or trades. Ergo, we need to draft one. Now, consider that overall the hit rate of QB declines as even round 1 goes by. If all goes well, we will not pick this high in the next two years. That is the time period during which we would have built the rest of the team and will be ready for a above-average QB. Hence, this draft is the right one to take a QB with our first pick. The only caveat is ofcourse that NIx and co have to be convinced that there is a QB worthy of being picked that high. I think we should not take a QB at all if not in the first round. Draft best talent if Gabbert, Newton are not thought of as atleast a Matt Ryan quality pick. If we dont draft this year, assuming we will pick in the middle next year, we can only hope a Roethlisberger or Rodgers is available.
