I have no doubt the Panther's vertical attack is still there when needed.
Shula is undoubtably utilizing the short pass to compensate for our offensive line, but it also allows Cam to advance the ball without being under constant threat of attack, controls the game tempo, keeps our defense fresh and opponents offense off the field. Where is the down side in that strategy?
Yes, eventually an opponent will attempt to take the short passing game away from the Panthers and force Cam to go long.
I suspect whoever that team is, they'll come to regret that decision.
