Am I missing the point of the original question? I assumed you meant where these three stack up compared to the production of wide receviers. Therefore, you were asking where they should be drafted in comparison to all other WR's.
Wide receivers catch the ball; so do TE's - and some of them catch it a heck of a lot more than other WR's.
In terms of production, last year Tony Gonzalez had the 19th highest amount of receiving yards (916 - that's a hell of a lot better than a whole lot of receivers), and only 3 receivers had more TD's than Tony did (10).
Heap had almost 700 yards and Shockey got about 500 in 9 games. Had Shockey played the whole year, he most likely would have been in the 700-800 yard range. 39 WR's had over 700 yards last year...
But, you start 2 or 3 WR's and only one TE - I'd much rather have one of these guys than someone that can't even outproduce my #3 WR, which are picked in rounds 5 through 10. Therefore in fantasy-land, they belong among the top 25 receivers.
Now, if you're in a league where you don't play a TE and just use them as WR's, I would mark them down a few spots, but Gonzo still needs picked in the top 20 receivers.
Pete, you would let Gonzalez slide all the way down to the 15th round of a draft and take someone like Robert Ferguson ahead of him (no offense Packer fans)? If Tony were still on the board that low, I'd probably faint and then laugh at all the other teams.
If you don't believe me, take a look at some of the mock drafts...there's no way Gonzalez is around past round 4 or the other two around past round 6.
