Great post FearTheLosing, I love the breakdown of the PFF stuff
My two cents . . .
I think just about every team in the league would like to improve some aspect of their o-line, it seems to be a constant theme. And, (this is anecdotal evidence, no real facts here--but why start doing that here on TBD ) it seems there are chronic o-ilneman injuries throughout the league.
That being said, there has to be someone out there on a practice squad, or an unsigned free agent, that could improve the LG spot. I guess Legurski is not the answer, or is still not physically ready to play. But, Marrone did say Brown earned the spot over him in training camp.
It's time to try something different, anything at this point.
