9. Wesley Matthews (Undrafted in 2009)
Wesley Matthews at one point was known as a top 5 shooting guard in the NBA and arguably the best two way guard in the NBA before his devastating achilles injury. Wes played 4 years for Marquette University where he completely flew under draft radars and left GMs dazed and confused as he emerged as a young star. Matthews was averaging a career best 16.4 ppg a few years back and started in all 82 games. The following year Wesley tore his achilles and sat the majority of the season.
Even with he major injury the Dallas Mavericks took a chance at this young star and signed him in the 2015 free agency period. Wesley is a nightly starter and looks like he won’t be the star the NBA envisioned but nonetheless at his peak he was definitely a top 10 undrafted player. Hopefully he bounces back from his injury and begins climbing up this list.
