Ponder is a Lock. You thinking otherwise is just foolishness.
Crownover is a lock. Just like Marcus Cannon was a lock.
Hollins is not 33 yet. You'd have a point about 4 teams in 4 years if he'd been cut from ANY of those teams. You also ignore the fact that Hollins was a binky for McDaniels in Vegas. Which is why he was brought to the Pats. Not to mention that Hollins has had 50+ targets in 3 of the 4 stops. The only one he didn't was Atlanta. Where he wasn't used properly.
Hollins more than proved himself last year and showed no signs of slowing down and his contract is team friendly.
