Recently, as was thinking about the new coordinators that Bradley brought in, I wondered whether it is more advantageous for the coordinators (assuming they are also the playcallers) to do their job o the sidelines or from the booth upstairs.
As I thought it over, I came to the not very uncommon answer of "it depends." On the one hand, if you are on the field, you can better communicate with the players and also get a feel for the mood on the field. You can also try to play the refs in your favor to get calls to benefit your team. On the other hand, if you are in the booth upstairs, you could eliminate all distractions, see the "chess board" from a better spot, and focus exclusively on calling a good game and executing the gameplan you spent the previous week meticulously preparing. Considering all of this, I think it does depend on the kind of person that you are; if you are a super analytical person who is not a very emotional individual, then you would be at your best and do the bet possible job from the booth upstairs. However, a more emotional person who could benefit from getting a feel of the atmosphere on the field would obviously benefit from being down there.
As a fan who does not get to see a whole lot of Jaguar games, I do not know what the situation has been in the past with the coordinators. Based on my criteria and what I know of the recent coordinators, I would venture to say Tucker and Koetter(who I know was upstairs in the NFC championship) were upstairs and Bratkowski(who I might recall seeing downstairs during the Thursday Night Colts game or the Jets game) was on the field. Am I correct? What about the new guys? Any idea what they like to do?
