Anquan Boldin has 101 catches for 1377 yards and 8 TDs his rookie season. Hell, Michael #######g Clayton broke 1,000 as a rook. I think him breaking 1,000 his rookie year is not nearly as unlikely as everyone thinks.
I'm going to say about 65 for 1075 and 7 and seriously move the kid up my rankings
In 2004, Michael Clayton had 80/1193/7. The next best WR on the Bucs that season was Joey Galloway who went for 33/416/5.In 2003, Anquan Boldin had 101/1377/8. The next best WR on the Cards that season was Bryant Johnson who went for 34/385/0.
Unfourtanately for Calvin Johnson, he has to compete with Roy Williams (82/1310/7 in 06) and Mike Furrey (98/1086/6 in 06) for touches.
In both Boldin and Clayton's cases, they were the unquestioned #1 WRs on their respective team as rookies, with little competition, who were just fed the ball.
If you plan on projecting big numbers for CJ, then you better bump both Roy and Furrey way down on your boards.

Ppl focus way too much on a guy's talent and ignore the situation he'll be in which is just as important.
I agree, but I think the situation is actually pretty GOOD for his chances. Yes, there was no competition for Clayton and Boldin, but these weren't exactly prolific passing attacks either.Let's look at the WR targets and receptions by team.
2006 DET 389 225 2859 12.71 145 14 370.90
2004 TB 253 179 2349 13.12 117 15 329.80
2003 ARI 304 158 2058 13.03 100 10 255.40
TB had 35% less targets and Arizona had almost 22% less. Of that, Clayton had almost 50% of the total WR targets (116/137) in 2004, where no other player had more than 20%. Boldin had WELL over 50% of the total WR targets, Bryant had a little less than 25%, with Gilmore getting most of the rest.
The interesting thing about Detroit is not just that they passed a lot, but that 75% of the total targets were shared by Roy and Furrey pretty evenly, and then there was basically no one else. These are numbers that look eerily similar to the 2003-2004 Rams offenses under Martz - Bruce and Holt getting the lion's share of targets, with Bruce being WR2 getting less but actually more receptions, and so on.
In other words, Furrey had only 37% of the WR targets and was the second option on his team, but still had more opportunities than Clayton, and not much less than Boldin.
Roy Williams is, no doubt, the cornerstone of that receiving corps right now. He is extremely talented from a physical perspective, and would probably thrive (or do well) in any system. I'm not totally sold on Furrey. I like him, I think he's got a lot of heart and speed, but he's not a world class physical talent. I think the numbers he put up were large in part because he was WR2 in a Martz offense.
So to answer your question, I don't think you have to bump Roy AND Furrey down the rankings... I think you have to bump one of them. If you think CJ can beat out Furrey fo r that WR2 spot, he very well could put up better numbers than either Clayton or Boldin precisely
because of his circumstances.
