Nick Giffen's Picks

Today
Tua Tagovailoa under 0.5 INTs (+105 at MGM/365) Might sound counterintuitive, but with 20+ mph winds forecast and even higher gusts, this is a great spot to fade interceptions, and Tua's prop offers the most value of the two QBs in this game INT rate drops just over 20% per pass attempt in high wind games, in part from attempts being shorter on average, and also harder to catch on deeper ones QB pass attempts also drop by almost 3 pass attempts per game in high wind games Tua's career INT per pass attempt is 2.21% since 2022. at 30.5 pass attempts (his current line, which I'd even lean under) with a 20% drop down to 1.77%, I'd get close to a 60% chance to stay under this, before adjusting for opponent As good as the browns defense is, they have only defended 19 passes on 169 attempts, putting them 11th worst in that department, and they've only converted 2 of those 19 into INTs which, on a per-game basis is 6th worst We're getting plus money on a QB that's solidly favored to not throw an interception. I'd be this to -125.

Denny is locked in and can help Bubba get the win he stole from him. Can also do 250-1 at 365 or 225-1 for the "straight forecast" at caesars (which is bubba 1st denny 2nd), but this allows for denny to be 3rd also in case he's pushing bubba by another car

Betting Highlights
Favorite Bet of All-Time
I bet on my favorite driver Kyle Kirkwood at 20-1 to win the Long Beach Grand Prix. I went to the race and watched him win it in person for his first career IndyCar win. It was the first time I watched him race an IndyCar in person, so I'm officially his good luck charm.
