The Patriots have spent most of their off-season fixing their roster. There's just one major flaw.
The New England Patriots had three major needs as they marched into free agency and the draft: 1) cornerback; 2) defensive line; 3) offensive line.
They've used both the draft and free agency to address the trenches. On defense, they've added Jabaal Sheard, in addition to three top draft picks on Malcom Brown, Trey Flowers, and Geneo Grissom. On offense, they used two fourth round picks on Tre Jackson and Shaq Mason to be long term fixes for the offensive line.
