I think this is a fair question because if you look at his numbers last year.

2011 Skelton's Numbers:

GP:8|PYD:1913|COMP%:54.7|TD:11|TD%:4.0|INT:14|INT%:5.1|Y/D:7.0|SK:23|QBR:68.9

Look at this projected numbers if he played a full season.

Skelton's projected number if he played the entire 2011-12 season

GP:16|PYD:3826|COMP%:54.7|TD:22|TD%:4.0|INT:28|INT%:5.1|Y/D:7.0|SK:46|QBR:68.9

These number's don't look nearly as impressive, but considering that Skelton posted 1913 passing yard and played half a season him going 4000 yards does not sound so crazy.

So with that in mind do you think he throws over 4000+ yards. I personally think he'll throw around 4200-4400 yards. If he can get his completion percentage to around 60% better I think it is certainly a possibility.
