Cleveland Browns quarterback Robert Griffin III still needs to work on his mechanics

quarterback Robert Griffin III was selected with the second overall pick in the 2012 NFL Draft by the Washington Redskins and the Redskins gave up the farm to get him which included trading away multiple first round draft picks. Griffin had a great rookie season in 2012 as he was named offensive rookie of the year.

But at the same time, his rookie campaign stalled about after suffering a knee injury at the hands of former Baltimore Ravens defensive lineman Haloti Ngata and part of the reason why Griffin suffered the injury was due to the fact that he didn't know how to slide.

Yes, four years later, Griffin is still having issues learning how to slide with the Browns. Learning how to slide is of Griffin's problems. The other problems Griffin has is his mechanics with dropping back under center and also knowing when to throw the ball away as the Cleveland Plain Dealer discussed below.

There are a lot nuances to being a quarterback, and the Browns are coaching Griffin in those areas.

But they also have three big messages:

1. Plant your back foot, then throw.
2. Get down, then slide.
3. Throw the ball away, don't take needless hits from the defense.

If you are the Baltimore Ravens, you have to like hearing that. And I'm sure the Ravens hope he doesn't learn anything by the time week 2 of the 2016 NFL regular season rolls around.
