I built my own test entry around the Florida State vs. Louisville game using a rushing-yards prop and paired it with an Iowa State vs. BYU passing-yards prop, exactly the kind of two-game line-up my Underdog bonus code bankroll supports.
Florida State vs. Louisville Preview with Underdog
Florida State vs. Louisville opens the night at 7 p.m. ET on ESPN. The Seminoles lean on a run game that carved up Virginia last week, while Louisville enters off back-to-back ACC losses decided by a combined six points.
That tight margin tells us that Louisville’s defense still competes possession to possession, setting Florida State’s rushing props up as a focal point for my pick’em entry tonight.
Underdog’s CFB lobby carries this into its rushing-yards and rush-plus-receiving-yards markets for Florida State’s backfield, so players following this matchup check out those props first before filling out the rest of their slate.
Iowa State vs. No. 8 BYU Preview with Underdog
Iowa State vs. BYU closes the slate at 10:15 p.m. ET on ESPN, and this one carries real stakes for the Cougars’ playoff push. BYU enters unbeaten and riding a physical ground attack. Iowa State’s run defense has struggled to contain opposing rushers through the first five weeks as well.
I like that mismatch for a BYU rushing-yards prop, and I’m pairing it with a receiving-yards look on the Iowa State side to balance my entry across both teams.
Underdog prices BYU’s ground game into its rushing-yards and fantasy-points markets, while Iowa State’s pass-catchers show up in the receiving-yards column, so players reading this preview check out both sides of the board before locking in a two-game entry.
Fans chasing college football futures watch BYU’s playoff case grow with every play, and that extra $100 bonus funds player prop entries across both games without touching a dollar of personal cash. Lock in the Underdog promo code TOPACTION now, scan the quick overview below, and build a lineup before Florida State and Louisville kick off at 7 p.m. ET.
How I Claimed the Underdog Promo Code TOPACTION

- When prompted, I wrote TOPACTION into the promo code field before finishing my registration.
- My $5 deposit came from my debit card linked to my bank account.
