In high school, Tim Boyle threw an INT once every 24 attempts. At UConn he threw an INT every 21 attempts. At Eastern Kentucky he threw an INT every 15 attempts. And in the NFL he’s thrown an INT every 13 attempts.
Tim Boyle has a 7.5% INT rate in the NFL. (League average is around 2.3%.) And he had a 4.7% INT rate in college.
How does someone like this make it to the NFL, much less as the preferred backup that is now starting?
Why is this even a question?
If the market’s price to get your car washed is $20 and I swoop in with a price of $10, by the law of supply and demand, I am still going to get work regardless of the quality.
Boyle hasn’t signed a contract more than 4 million yet since being in the league and a back up that you can sign for the league minimum is something teams may always take advantage of.
