NFL hopeful Manti Te'o has been having a rough start to 2013 and with his unimpressive 40-yard-dash time over the weekend, there are now added question on whether the young lineman has what it takes to be successful in the NFL.

Te'o has garnered so much attention in recent months that even the NBA's Miami Heat were watching the 2013 NFL Scouting Combine prior to Tuesday night's game against the Sacramento Kings. However, what was interesting about that is what Miami's LeBron James had to say.

When asked about his own 40-yard-dash time, James said he ran the sprint in 4.6 seconds over the summer, according to South Florida Sun-Sentinel's Ira Winderman:

According to Winderman, James' didn't stop there as he was quick to point out his time came without training and that it was superior to the former Norte Dame star:

James is already considered as somewhat of a freak athlete as it is. Listed at 6'8" and 250 pounds, James also reportedly has a 40-plus-inch vertical leap and is largely seen as one of the NBA's strongest players.

The 28-year-old three-time defending league MVP has been described as a freight train in the open court, blessed with the combination of strength, speed and quickness that has rarely seen on an NBA hardwood.

Meanwhile, Te'o's poor athletic showing became one of the biggest stories on Monday. His recorded time of 4.82 seconds in the 40-yard dash was the seventh-worst among all linebackers who ran during the on-field drills.

Even after finishing second in the Heisman balloting in 2012, Te'o's draft stock has been in free fall.
