So our max protect is simply putting out an extra TE, FB, or RB into the back field. All of these are elligible recievers and all are used extensively in the running game. All are also expected to run routes when they don't have a man to block. TEs run outs or short curls, FBs and RBs slip out to the flat for an outlet.
Having said that, we lose nothing by having another TE on the field. Our second TE is better than our third WR.
Keeping the RB back to block has been a mixed bag. I focussed in on the blitz pickup of both Barber and Jones on Monday. This I can say for certain, both are really good at picking up the blitz. I saw Barber absolutely blow up a linebacker coming on a delayed blitz. However neither has been able to provide any kind of threat as a reciever in the flat. This is mostly Drews fault. By the time he checks down and passes it to the flat he has given the linebacker time to close the space. You want to force teams to keep a man in coverage to your RB, which is impossible if they aren't a threat to gain substaintal yards.
Polite has shown decent hands and decent run blocking. However he absolutely was the reason for at least one sack on Monday. He should have been right off the RTs hip to pick up the delayed blitz while the Running back took the outside blitzer. Instead he went with the outside blitzer and gave up the lane directly to Drew. We lose something on offense by having Polite back there. It certainly is no coincidence that BP (or Sean) has drawn up plays putting Keyshawn, Pierce, Spears, and Witten back in the FB spot. I wouldn't be surprised if we upgrade this position.
Overall I don't think max protect has cost us much. Glenn is fast enough to get behind coverage and Drew has shown good accuracy.
