Oh come on guys. CaptKirby, you even mention that Eli airs it out more than Romo to discredit Eli's yards, but don't take into account that taking more deep shots leads to a lower completion rate? Eli's completion % was 5% lower than Romo's, but his Y/A was still higher (8.4 to 8, as for the others mentioned - Freeman 6.5, Alex Smith 7.1, etc, Matt Ryan 7.4).
Your response will probably be to discredit his yards because of Cruz, but taking away Cruz and his 131 targets (

And that's not really fair because you'd be assuming that someone else doesn't take over for Cruz as a deep threat - if you do the same with Brady and take away Moss' 159 targets for 1500 yards in 2007, his Y/A drops from 8.7 to 7.9. Do the same with Rodgers and take away Nelson's 95 targets for 1250 yards (

Tony Romo's a great quarterback, no doubt about it. The one thing that Romo does better than Manning is that he doesn't throw as many interceptions.
But Manning can improve on the interceptions. Gilbride's offensive system depends a lot on reads after the snap - which works great when the receivers and QB are on the same page, but it's also why you'll see Manning seemingly throw to nobody (accounts for a good portion of his interceptions). It's why Steve Smith and Toomer played such important roles in the offense - not because of amazing athleticism but because they knew the system (and it's why Hixon is the 3rd receiver now even after 2 ACL injuries as opposed to Randle or Jernigan). Gilbride ran a similar system with the Houston Oilers, and Warren Moon threw for a lot of yards/TDs but also high numbers of interceptions.
Since 2006, the receiver with the most receptions has changed every year except between 2008 and 2009 (2006 - Shockey, 2007 - Burress, 2008 - Steve Smith, 2009 - Steve Smith, 2010 - Nicks, 2011 - Cruz). Generally, Eli has had only 2/3 years at most to develop chemistry with his targets over the years before having to start over with new receivers, and I think it's hurt his development. We'll see how he plays this year with Cruz in his second year (ignoring his injured 1st year) and Nicks in his fourth.
