nfl-stats | getting NFL team , player and game data | Analytics library

I'm still leaning how to utilize beautifulsoup. I've managed to use tags and what not to pull the data from Depth Chart table at https://fantasydata.com/nfl-stats/team-details/CHI

But now I'm try to pull the Full Roster table. I can't quite seem to figure out the tags for that. I do notice in the source though that the info is in a list with dictionaries, as seen:

So I'm pulling statistics of NFL players. The table only shows max 50 rows, so I have to filter it down to make sure I don't miss any stats, which means I'm iterating through the pages to collect all the data by Season, by Position, by Team, by Week.

I figured out how the url changes to cycle through these, but the iteration process takes so long, and was thinking: we're able to open multiple webpages at one time, couldn't I be able to run these processes parallel, where each process simultaneously collects the data from each page, stores it in its temp_df, then merge them all at the end...instead of collecting one url, by one url, then merge, then next url, then merge, then next,......at a time. Meaning this iterates through 6,144 times (if I'm not iterating through the positions), but with the positions, over 36,000 iteration through.

But I'm stuck on how to implement it, or if it's even possible.

Here's the code I'm currently using. I eliminated the cycle through position to just give an idea of how its working, which for quarterbacks, the p = 2.

So it starts at season 2005 = 1, team 1 = 1, week 1 =0, then iterates all those to the last season 2016 = 12, team 32 = 33, and week 16 = 17:
