Les also liked Charles Johnson (WR, MIN) a couple years back for similar reasons. Not throwing shade, rather making the point that these are dart throws and they work out 10-20% of the time on average.
Maybe less..............some will be a Tyrell Williams, Julian Edleman, etc, most will not. The key is if the news flow doesn't continue positively move on. I wouldn't call 'em dart throws although I think I know what you mean. If you pick up a guy based on talent plus situation/news flow it helps define the reasons for holding....and the reasons to eventually drop.
