Right Doomsday, Offensive tacke is really hard to learn, then if you take in, it takes 2-3 years for offensive line to jell together, makes it really tough. Next, you have the Giants 2 dominating defensive ends teaching you a lesson too.
Added into that, Petti was 360 at senior bowl or close to it. But his senior year, scouts reports had him listed at 6-6, 329 and 5.16 in 40. He even dominated the quick defensive end from the colts-Dwight Freeney. And we all know how Freeney killed Flozell Adams one year with his quick pass rush.
True about Tuneii, he played for like 6-7 years before he came into his own. I still think though Rob Petti reminds me of Erik Williams, 6-6 330, with 5.16 in 40 yard dash. And we all know how mean and nasty Erik was, along with talented. I dont think Rob is quite that athletic, but he is close, if he works on it.
Got to remember he had some kind of foot injury. Another guy you can put in that category that was even a free agent is Nate Newton, if you remember the first 2-3 years, with Jimmy Johnson, Coach Johnson even put Newton at right offensive tackle, he was best we had till Erik Williams came into his own. Jimmy Johnson installed him as starting right tackle in 1990. He was named the Cowboys' Offensive MVP by Pro Football Weekly. He moved back to left guard when Erik Williams came along. With Nate making some pro bowls himself.
