Geeky Recruiting Data Shit

I am learning how to use some data visualization software, so of course I am playing around with TBS data.

The data is Rivals recruiting database. I'd prefer to use the 24/7 Composite rankings, but scraping that shit from the web is a major PITA.

    Based on this analysis, Ty just needed more time.

    It was his least terrible class, on paper. In reality it was pretty awful, though Polk, Kearse, and Ta'amu were special.

    I prefer DDY’s recent outlook of positive developments in our DL recruiting.

    Need @Dardanus to confirm

    Stanford appears to be way more talented than us. I'm not sure but we're third now behind USC and Stanford

    We sure sucked for a long tim

    The funny part is the dip beore UW's rise was Pete's first class which ended up re-ranked as the best in the Pac that year.

    You can clearly see the inflation in the grading system. Everyone other than Cal and the Arizona schools trending up.

    Pretty good start @AIRWOLF. Couple things I would consider:

    1. Sort/order by star ranking (best to worst), not alphabetical. The idea is you want to show the important information in order.

    2. The message you send with a line chart is greatly affected by aspect ratio. There is no perfect ratio, but generally 2:1 (w:h) is about right. In this case, a 0.2 star ranking change is a steep increase or decrease. Columns or bars might be a better choice.

    3. Are you trying to emphasize the trend over time, or compare average ranking of each school? Comparing rank of each school can be done much simpler (11 bars ordered by avg rank over this time period, Cal excluded of course).
    Comparing the trend of multiple items can be difficult in a limited space. A good method is to put all lines on a single chart, with a selected school using their color, all other schools being gray/semi-transparent in the background. Your visualization tool might not do this, though.

    4. Be careful web-scraping TBS stuff. My cousin had the FBI knock on his door for similar activity. Not good.

    Do you even Tableau, bro?

    Seriously though, thanks. I have tons more I need to do with this, but I am a retard with this software.

    A lot of it is stuff I have done in Excel before, just not over as long a time period.

    I really am doing this first and foremost to learn how to use the stupid software. Simple things like changing the colors of the lines and formatting things are easy once you know how to do them, but they are not easy when you don't.

    Yeah. There is certainly grade inflation going on. The Sum total of the average Stars for the Top 100 teams has risen steadily over time.

    I am going to work in a viz (look at me using serious geek lingo) on that too.

    We understand better than most... It’s hard

    Chinspiring. Time to gogo data science.

    Created a shitty heatmap with dendrograms, interpolating the missing games so we get to play EVERYONE.

    Rows are offense, columns are defense.

    Spoilers: we lose to USC and are a tossup with dickrod thanks to our shitty offense. Our defense is clustered similarly to USC and Stanford, our offense is similar to that of ASU.

    Yep, Tableau is great. It can definitely create the dynamic line chart. This poast may help (the "data-ink" concept is what I was trying to get at).
