Don't get too bogged down in lagging indicators, though. Look at the trend.
OSU - 2 catches on 8 targets (2/8 - 25%) for 35 yards and 0 TDs.
SJSU - 4 catches on 8 targets (4/8 - 50%) for 30 yards and 0 TDs.
UTEP - 3 catches on 6 targets (3/6 - 50%) for 32 yards and 1 TD.
SHSU - 4 catches on 6 targets (4/6 - 66%) for 93 yards and 2 TDs.
He's steadily improving in terms of receptions. Even though he stalled a bit against UTEP, the SHSU game is a positive sign and suggests he may be over the hump. A single line of statistics don't tell the story, you have to look at the trend.
And I will readily admit that the "trend" is hardly definitive, because there is a small sample size. As I said above, my point is not that there is no problem whatsoever, just that we can't definitely say there is a problem because of the small sample size. And if there was a problem, hopefully it's fixed.
