Some players used the 2013 NFL Scouting Combine to make a bunch of money by improving their draft stock.
Unfortunately, this slideshow isn't about those happy campers. It's about the guys who might have cost themselves some serious future compensation.
It's important to note that not all red flags are created equal. Some are injury concerns that will likely be resolved; others are dumb decisions that can be explained away.
However, some are a physical deficiency. For those players, the sting of the combine could very well linger until draft night.
It's also smart to remember that a red flag doesn't mean certain doom. There's plenty of time in the next two months to paint a different picture.
But that doesn't mean it will be easy.
