Above you can see Ross' receiving stats for 2014. They are separated into two categories: gains over and under 50 yards. He is clearly a home run threat, with a majority of his receiving yards being on plays > 50 yards.
The non-big play stats are not bad, but not great either. I'm not throwing out his big plays to make a poont, just separating to evaluate. Note: the 11 incomplete passes could be split between over/under 50 yards...there is no record of how many yards incomplete passes are.
One interesting thing I found (shown above) is that Ross was targeted four times on 3rd down (3 receptions, one incomplete). Of those 3 receptions, UW needed 14, 22, and 8 yards for a first down, while the completions were for 1, 16, and 6 yards, respectively. Meaning, of the four targets on 3rd down, ZERO resulted in a first down. Of course..QB, Jonathan Schmith, blocking, other receivers not being open, injuries, climate change, Ossai, etc. could ALL be factors in determining why UW didn't convert on first down.
I would say that Ross's elusiveness and speed makes him a deep/big-play threat, but in short or intermediate yardage situations he is not a guy you want to rely on. Definitely worth three wins all by himself, though.
