Bigger, Faster, Stronger

9/21/2014 Matt Chambers 6 Comments

I recently attended Tableau Conference 2014, and I attended a session given by Andy Kriebel, Jewel Loree, and Peter Gilks. The session was focused on starting a data blog as a means to build a portfolio using publicly-available data. I was so inspired by the session that I decided I would start my own data blog. I had been browsing a few datasets, and I found an awesome dataset on NFL Combine data.

When I looked at the data, I wanted to visualize the impact of forty-yard dash and max repetitions of 225 on draft position. Once I finished those, the theme of the visualization started to come together as Bigger, Faster, Stronger. Initially, I looked at the players just by size, but the more interesting analysis for me was finding the players who are both big and fast.

The Bigger visualization actually looks at the combination of speed and size. First, I calculated the surface area of the player's body by using this calculation. I then divided the player's forty-yard dash time by the player's body surface area to calculate the Speed to Size Ratio (SSR.) I suspected that Calvin Johnson would possess the most elite combination of size and speed, but the analysis confirms it as well.

Here is the final product:

  4. Hello Everyone, i am DAVID HILL MILLA now living in FLORIDA. I am SINGLE DAD, at the moment, two children and I was struck on the financial situation and need to refinance and pay for my son's medical bills and school fees. I tried looking for different loan lending companies and private corporation but never got a loan from them, and most banks reduced their credit. But as God would have it, I was introduced to the private loan lender JULIA NAVARO CEO NAVARO LOAN COMPANY and I got the loan amount ($553,760 USD), and today I am a business owner, and the kids are doing well at the moment. So, my dear friends, if you need to contact referring to all the companies that provide the loan at low interest rate of 2% and better repayment plans and schedules, please contact (JULIA NAVARO) at Navaroloancompany@yahoo.com. I'm so happy now, and I decided to let people know more about it, she offers all kinds of loans to individuals and company, and I want God to bless her. You can contact the company via e-mail (Navaroloancompany@yahoo.com)....
