Because they desperately need help at receiver and can bring back Jason Peters as a stopgap.
It’s still completely asinine of them if they think Dillard has ANY chance to be a long term LT for them.
I’d want 21, Dillard, Douglas and 88.
Our value is 1250 for 11. 21 and 88 is 888 points, meaning we would value the combo of Douglas and Dillard at 362 points, or roughly pick 53 (Phillys second rounder), so I think I’d probably want a 4th to go with it.
