Whether you believe they get a fair shake or not, short quarterbacks don’t tend to find sustained success in the NFL very often.

For every Drew Brees or Russell Wilson, there are a truckload of other passers who can’t seem to overcome their lack of ideal size and secure a long-term starting job at the game’s most important position.

That could make things interesting for one of this year’s top quarterback prospects, North Carolina’s Mitch Trubisky.

Though he’s listed at 6-3, NFL Network’s Mike Mayock is expecting him to measure much shorter at the NFL Scouting Combine (via Dan Kadar of SB Nation):

In the last 15 years, only two quarterbacks 6-1 or shorter have been drafted in the first round: Johnny Manziel and Rex Grossman.

Trubisky’s skills as a passer are much better than those two guys, but it’s certainly worth noting, considering how rare it is for shorter quarterbacks to have significant success at the next level.

If Trubisky indeed measures close to 6-1 instead of his listed 6-3, don’t be surprised if that has an impact on his draft projections, which currently have him coming off the board as high as the No. 2 overall pick.
