Are you kidding? T.O. has gone over 1100 yards receiving the past five years and six of the last seven years. The last time that Terrell didn't score more than 8 TDs was 1999. He's a threat to score a TD every time he touches the ball. If it weren't for Randy Moss, Terrell would be the best WR in the NFL. He makes whatever QB he's playing with better.
Anquan Boldin had one good year, and last year he scored one TD and didn't have an impact in any of the Cards' wins his big rookie year.
The biggest comparison between T.O. and Anquan is that they wear the same number. News flash, buddy, the primary WR in the Valley wears #11. Anquan's being moved back to the slot because he was ineffective on the outside.
Anquan Boldin is probably a Top 5 or 10 #2 WR. Overall, though, I don't know if Anquan Boldin is in the top 25 at his position in the league. Very quickly, here are 20 wideouts all better than Anquan:
1. Randy Moss
2. Terrell Owens
3. Marvin Harrison
4. Javon Walker
5. Torry Holt
6. Hinz Ward
7. Chad Johnson
8. Mushin Muhammed
9. Derrick Mason
10. Rod Smith
11. Lee Evans
12. Darrell Jackson
13. Plaxico Burress
14. Jimmy Smith
15. Andre Johnson
16. Joe Horn
17. Eric Moulds
18. Chris Chambers
19. Roy Williams
20. Larry Fitzgerald
Hope that clears everything up for you.
