Three quick hits on the Denver Broncos:
Can Orton get the job done: We knew Kyle Orton was going to be under pressure in Denver this year. You don't replace a player the caliber of Jay Cutler and not have pressure on you. But we didn't expect the heat to be on Orton so soon. But it is. Orton struggled at an open scrimmage at Invesco Field on Thursday night and was booed roundly by the crowd. If Orton doesn't improve, fans are going to get increasingly impatient with him. Denver got used to Cutler's strong arm very quickly. Orton's much less impressive arm is making folks in Denver nervous.
Knowshon needs to get to know the offense: Denver top pick Knowshon Moreno signed Friday after missing a week of training camp. It was paramount the running back, who was the No. 12 overall draft choice in April, sign his deal. He is expected to be a vital part of the Denver offense. If he can catch on quickly, Moreno should become Denver's primary back soon. Denver didn't use the No. 12 pick in the draft for a part-time player -- not with all of those needs on defense. Denver coach Josh McDaniels thinks Moreno can be a three-down back. He will be pushed into serious playing time soon now that he is signed.
The defensive line is green: Denver's defense needed major repairing this offseason and the Broncos worked hard to improve the secondary and linebacking crew. But the defensive line remains a major weak spot. The team's current three starting defensive linemen are ends Kenny Peterson and Ryan McBean and nose tackle Ronnie Fields. These three players may become quality players, but they aren't yet. The group has combined for just two NFL starts in the past two seasons. Denver's defense can't be counted on until this group proves itself.
