"The guy who's coming in on a tryout means that everyone had a chance to draft him and they passed," the agent said. "And then everyone would have had a chance to sign him to a free-agent contract and they passed. So it's that next level. Usually they'll sign a couple of guys."
Of course, there are some financial differences. There's a modest amount of guaranteed money invested in an undrafted free agent, while a tryout player isn't guaranteed anything.
"The main difference is if you're an undrafted free agent, you sign your contract immediately," the agent said. "If you're getting invited for a tryout, you're not signing a contract. You're basically going out there with a two- or thee-day tryout and then they decide out of this pool of 15 or 20 guys they brought in, 'OK, we're going to sign this one or that one.' Then at that point, (tryout players) sign their contract as an undrafted free agent."
