Well, maybe this is why Tyrone Crawford is still on the roster. He's overpaid, sure, but the Cowboys at least have an experienced alternative in case McCoy is done for the season.
what case ?
Crawford won't be able to be an immediate replacement starter at DT.
He was actually replaced in starting lineup with Maliek Collins in 2016, because he was too light in the azzz, to hold up vs the run in 2016.
he offers nothing at DE as a edge rusher outside, and he's suited more an a part time, rotational nickel rusher
And at his age, his medical concerns (double hip surgery) and his recent trend of injuries (shoulders, hip) Crawford himself could
likely be subdued by injuries that takes him out for an extended time as well.
