I disagree about Felix Jones' receiving skills.
Skip Pete has already hinted that the Cowboys want to get Felix Jones the ball through the air, in order to supplement his anticipated increase in the running game work load. You can't do that by yanking him off the field on third down all the time. The Cowboys have been working him in the passing game a bunch, and he's going to get his opportunities to catch the football this year, imo.
Marion Barber's rookie year receiving:
18-115-0 LG 21 6.4 AVG
Felix Jones second year: (only caught two ball his rookie year)
19-119-0 LG 30 6.3 AVG
Felix Jones catches the ball very well out of the backfield, and that is fundamental to being a RB.
The slot receiving and running WR routes is icing on the cake for Jones, and he's working hard on it and has improved in that area.
Barber saw a jump in his receiving output during his 3rd year.
44-283-2 6.4 AVG
I expect Jones to be much more involved in the passing game this year; he catches the fundamental RB balls well. I seem to recall him catching a floating throw with one hand and getting good yardage on it. When Dez Bryant is on the field, there is going to be even more space for Jones to operate and get space in the running game and receiving. Jones is simply too explosive of a football player to have standing on the sidelines on third down.
Jones caught only 4 balls in the two playoff games and had 52 yards.
That is a 13.0 AVG, and the long was 30 yards against the Eagles.
It might be wise to throw it to him more, and you can't do it with him on standing on the sidelines on the money down in the NFL.
