Looking at the End of the Regular Season projected standings, 21 of the projected top 24 made it to round 2. DoctorKz (21st), bardin (22nd) and slainte (24th) missed round 2, while justinlee_24 (25th-t), Relkcirts (25th-t) and fooolishfool (27th) all made it. The difference, of course was projected vs. actual playoff bonus points. bardin was-19, slainte -14, DoctorKz -13 while justinlee_24 is +6, Relkcirtsis +12 and fooolishfool is +6 (all three are still playing).
So in essence, playoff results acts as somewhat of a tie-breaker for those people right on the bubble.
Interestingly, nobody with only 2 playoff teams made it to round 2. mllama54 was the closest (finishing 26th). He was +9 with his two playoff teams, but really needed to have at least two World Series appearances (or a WS win and LCS appearance) to have a shot.
