Jack Kemp was a late-round (17^th) pick in 1957 by the Detroit Lions, but he never played a down for them and would find back-up work with the Pittsburgh Steelers that year.  Kemp would later be on the taxi squad for both the San Francisco 49ers and New York Giants but would not see any action, though this would change with the formation of the American Football League.

Drafted 8^th overall by the San Diego Chargers in 1986, Leslie O'Neal made an immediate impact in the NFL by winning the Defensive Rookie of the Year and accumulating 12.5 Sacks.  He suffered a knee injury that took him out for a year and a half, but by 1989 he was ready to return, and he was named to the Pro Bowl in six of his next seven seasons, each time recording at least 12 Sacks.  O'Neal was one of the most ferocious pass rushers of his day, but his interrupted prime and time with a Chargers team not known for defense have impacted his overall legacy.

O’Neal finished his career with St. Louis and Kansas City and would retire with 132.5 Sacks over his career.

Jessie Tuggle went undrafted out of Valdosta State, but the home-state Atlanta Falcons signed him, and he went on to a 209 Game career, all in the Peach State.  Tuggle was at Inside Linebacker for years before moving to Middle Linebacker, but regardless of where he was in the interior, few NFL players could tackle more efficiently than he could. 

A five-time Pro Bowl Selection, Tuggle played his entire professional career with Atlanta, but that didn't necessarily mean he drew much attention outside the ATL.  The Falcons were not good for most of Tuggle's career, and that undoubtedly led to plenty of tackling opportunities.  He would lead the NFL in Combined Tackles four times (1990, 1991, 1992 & 1995) and had seven seasons in the top ten.  The Falcons improved late in his career, and he tasted playoff success and played in Super Bowl XXXIII.

As of this writing, Tuggle is the all-time leader in Solo Tackles.  You have to think that anyone who leads the National Football League historically in the critical metric of Solo Tackles (albeit, this stat was not always kept) should give him a (small) chance for Canton.

Joe Fortunato played his entire career with the Chicago Bears, the team that drafted him in the 7^th Round in 1952. 

While the Linebacker was chosen for the 1950's All-Decade Team, many of his accolades took place in the 1960s.  Four of his five Pro Bowls came in the '60s, as did all three of his First Team All-Pro Selections.  As for his team accomplishments, Fortunato was a vital part of the 1963 Bears Championship Team.  He would record 16 Interceptions and recover 22 Fumbles over his career, the latter of which was a record when he retired.   Not too bad for a guy who looked undersized for his position!
