Why would they be expecting big production from Harty and Sherfield?
Two undrafted free agents, one of whom is 5'6" tall, who have shown glimpses of talent but never consistent production.
If what you are thinking is true and their plan for this past season (or any season) was to get big production from Harty and Sherfield then these guys are clueless... It's a lousy plan. If that's their idea of good enough....it's not even close to good enough.
They should have foreseen years in advance the tight cap coming with Josh on his 2nd contract. They should have drafted a couple/few talented young wrs in the top rounds over those 5 or 6 drafts to develop and have on rookie contracts. Instead they trot out undrafted free agents and hope for the best while constantly building the dline with top picks and expensive fa pickups; and once again the defense is statistically good but too soft to stop the good qbs when it really matters. It doesn't matter how good your players are when you line up 8 yards off the line on 3rd and 4. I hear people say it's time for another def line rebuild....
