I watched these last week sometime, but didn't get a chance to comment so here goes.
I thought Rex's accuracy was amazingly good, and it seemed like he could pretty much make all the throws. Many of those passes he made do not get completed if McNabb is back there. It's exactly why Rex looked so much better than McNabb in running the offense.
The biggest flaw I see in Rex is that his pocket awareness is horrible and he doesn't do a good job of securing the ball. Also, I noticed a few of his balls batted down. Possibly his height playing a factor?
This was brilliant Dirtbag...lol
*hats off*
