Johnny Manziel will this Friday learn where he will begin his career in the NFL.

But whilst the former Texas A&M quarterback may be excited to get going in the pros one stat released by ESPN recently should get fans of Johnny Football a little worried.

Manziel of course was awarded the coveted Heisman Trophy during his freshman year but it is this fact that leaves him in unwanted territory.

The table, which can be seen here, depicts the pro careers of Heisman winning quarterback going back the past 25 years - and it doesn't make pleasant reading.

There have been fifteen QB winners of the award since 1989 (not counting Manziel himself or 2014 winner Jameis Winston) but it certainly seems their college careers were a high-point.

With an average pro career for the NCAA's best lasting just 3.8 years, they have a combined losing record of 159-203 without ever making a Super Bowl start.

Recent winners, Cam Newton and Robert Griffin III (along with USC's Carson Palmer) have at least made it to the Pro Bowl so there is hope for Manziel yet.

The former Aggie has never been one to lack confidence however and will hope to disprove the theory when he finally enters the NFL this week.
