I have often wondered how much our o line coach had to do with our poor performance. I suspected the prior coach was lacking, but how can you tell?

This may not mean anything, but Colon was on Sirius NFL yesterday and he said he had already learned more in a couple days than he did the prior two years.  He quickly pivoted and said the old coach was great, but..........

May mean nothing, may mean something. I am just a fan, but I thought our line was poorly coached. Maybe, just maybe it will improve.
