Out of all our problems, that seems like the least important thing to worry about.
You can be successful with small or tall receivers – you recruit the best you can find/get. If there are two receivers of equal speed, athleticism, hands, and skill and I could only take one, I’d take the taller one 10/10 times. It gives a bigger target, more mismatches against defenses, and usually longer wingspan.
Unfortunately, we’ve struck out on most of our top tier and second tier WR targets over the past several years, both short and tall. Combined with the lack of development in that position, our only real success has been with transfers (absent AL). I’m more concerned about having more than one capable receiver each year than I am with their size.
