He was a turnstile liability at LT.
The Steelers used their last two 1sts drafting a replacement, because they knew he was subpar, but then they did not use either 1st to replace him.
Either horrible drafting or bad player management, you pick.
Dan Moore Jr was not good enough to play LT and that has been obvious for 3 seasons.
And he may be moved to RT! That thing they couldn't do for the past 3 seasons because his one leg was shorter! 3 years with Steelers: cannot move him from LT. Day one on new team: why not try it?
