Just a few online sports books have placed lines for the forthcoming NFL Combine. This is likely more of an attention/click grab as history has shown there's a ton of value in betting on the combine given adequate preexisting knowledge and research. Here's a few bets I love:
Will Byron Jones' 12'3" broad jump record be broken? (No, -165)- This is one of the worst lines I've ever seen. Jones' 12'3" broad jump is the world record and no combine participant has posted a jump within 6 inches of the current Cowboy's number. Julio Jones' jump of 11'3" was considered freakish- that's an entire foot less than Byron Jones' jump. This bet should've started at -5000 and really should be closer to -10000. If there weren't limits, it's an empty the account type wager.
Will John Ross' 4.22 40-yard dash record be broken? (No, -250)- Similar, but not as extreme as the broad jump line. Ross ran a near perfect time last year, so fast that his leg seized up in the middle of the run. LSU's Donte Jackson and Ohio State's Denzel Ward are probably your two best bets as challengers, but odds are those two are closer to 4.30 than a 4.20.
Derwin James vertical jump O/U 38.5 inches (Over, -160)- It's hard to fudge a vertical number and James has been posting jumps over 40 inches with consistency at Florida State. As seen in this video, James has bunnies.
Derrius Guice 40-yard dash time O/U 4.38 seconds (Over, -180)- This was a good bet on its own, but Guice has since weighed in at 224 pounds. Just two running backs have run sub 4.40 times the last two years. For comparison, CJ Spiller ran a 4.37 at 196 pounds.
Baker Mayfield 40-yard dash time O/U 4.69 seconds (Over, -160)- Johnny Manziel ran a 4.68 and had a much more distinguishable top gear than Mayfield, who is more of a high 4.7 to mid 4.8 type. He's also been more focused on positional training than testing. Mayfield might have a good start and agility times, but it's doubtful he runs a 4.68 or better.
Faster 40-yard dash time Josh Allen or Josh Rosen (Allen, -220)- Josh Rosen ran a 5.03 in high school and Allen is expected to run somewhere in the 4.7's. That's before we get to the sizable gap in their on-field play speeds.
