When you think of Miami Dolphins left tackle Laremy Tunsil you think of a key building piece on the offensive line. A player that should have been in the pro-bowl last year. A player who had his best season as a pro. If you ask new offensive line coach Pat Flaherty about Tunsil, he will tell you he has room to improve.
It seems that is all we need to know about Flaherty as a coach. If he looks at the best offensive lineman on your team and says, “yeah, he is good but can be better” then he is a coach is going to demand a lot from his players.
