This is the point I keep trying to make. And let's take the math a little further:
Wes Welker had the most snaps of any WR with 67. That's almost four times as much as Ocho's 18. We'll say 3.5 for simplicity.
in Ocho's 18 snaps, he made 1 catch and should have had a 2nd but was mugged with no call. So two "catches" in 18 plays. Multiply it by 3.5, and the guy's making 7 catches (a 112 catch pace over 16 games). So his productivity (in a very limited sample size) was NOT bad. The problem was you had two guys with at least four years in the system available, and you wanted to run a 2-TE no huddle (where knowing the system is probably the most important thing).
And I don't see this changing too often unless there's an injury. It's just a numbers game and the other guys have been here long enough to be Brady's second brain.
