Wentz is set to become the fourth non-FBS quarterback selected in the first round since 1979 and the first since Flacco in 2008. Many draft experts believe Wentz will be selected No. 2 overall by the Philadelphia Eagles.
So, what would be Flacco's advice for Wentz?
"If you're a good football player, it doesn't matter where you played at, and I think that's especially true as a quarterback," Flacco said on the Ron Jaworski Show on 97.5 The Fanatic.
When Flacco was drafted No. 18 overall in 2008, he went from quarterbacking Delaware to throwing passes in the AFC Championship Game. He believes the key is not to become overwhelmed mentally. It's all about maintaining confidence.
Flacco can see how it can be tougher for offensive linemen from a non-FBS school to have a more difficult time with the transition because a blocker can be bigger and stronger than the defender he's lining up against in college. It's not the same for quarterbacks in making the jump from FCS to the NFL.
"When you're a quarterback, it's all relative to a certain point," Flacco said. "You're not throwing to a 6-foot-4 receiver that runs a 4.3 against all I-AA corners. The windows are the same. It might not be technically as fast as some of the higher-level games. But, at the end of the day, the window is just as small because everyone on the field is notched down a little bit.”
Beyond the small-school roots and size, there's not a lot of similarities between Flacco and Wentz. Flacco has the much stronger arm, and Wentz is the more mobile quarterback.
At the NFL combine two months ago, Wentz credited Flacco as helping to pave the path.
“I think the success of guys like Joe Flacco or Tony Romo and the list goes on whether it’s quarterbacks or other position players,” Wentz said. "Especially a guy like Flacco coming in really right away as a rookie and winning some ballgames I think shows that that adjustment can be made by special players, for sure.”
Flacco set the bar high for small-school quarterbacks after winning the 2012 Super Bowl and being named the game's Most Valuable Player.
If Wentz is drafted by the Eagles, Flacco doesn't see it as tremendous pressure for Wentz to go to a franchise that has never won a Super Bowl. Flacco considers it a prime opportunity.
"If you come in here and you were to be the first guy to win a Super Bowl, shoot, he'd be bigger than Jaws [Ron Jaworski],” said Flacco, who grew up in Audubon, New Jersey, which is 11 minutes from Lincoln Financial Field. “I don’t know that a person would be brought into a community better than here because of what these people here have endured here for the last 50 years.”
