• There is no question Devin Hester has the lateral ability and vertical speed as a receiver to put pressure on opposing defenses, but how do the Bears plan on getting him the ball?
• Rookie defensive end Shea McClellin has the size/speed measurables to turn the corner and apply pressure to the quarterback, but that's not enough in the NFL. When the pads go on, McClellin has to focus on counter moves, hand placement and overall skill set to become a productive pro edge rusher.
• Getting Gabe Carimi back as the starter at right tackle is a major upgrade for this Bears' offensive line. Even with the competition at left tackle between J'Marcus Webb and Chris Williams, solidifying the right side is a key to protecting quarterback Jay Cuter.
The Bears can cover up one side of the line with play calling and protection schemes, but they must have a solid tackle to lean on. I think its Carimi.
• I don't doubt Major Wright's ability to play safety in the NFL. Wright can run, has enough range and will fill on the run in Smith's base schemes. However, his discipline and technique in the deep half must improve for him to become a consistent playmaker.
• I like cornerback Tim Jennings' toughness, his willingness to set the edge of the defense in Cover-2 and his reliance rely on technique in coverage.
Adding an experienced veteran to the mix in Kelvin Hayden will force some accountability from Jennings to compete daily. That's smart.
• Receiver Brandon Marshall has a top-five skill set and the Bears have multiple ways to utilize his talents — run stack looks, align him out of position in the slot, throw the 3-step game (slant) and use deep play-action. A true No. 1 receiver opens up play-calling possibilities.
• Tight end from a scheme perspective in offensive coordinator Mike Tice's offense will be interesting to watch. Look at matchups here between the numbers with Kellen Davis and don't forget about rookie Evan Rodriguez when the Bears use their Ace personnel (two receivers, two tight ends, one back). Rodriguez played with much more speed Thursday than I saw in minicamp and his conditioning has improved.
• With Matt Forte under contract and the addition of Michael Bush in the backfield, the Bears have two running backs who can run in-between the tackles and control the tempo of the game. Think power football in the NFL, plus the stretch and zone plays from one-back alignments. That still sells and leads to vertical opportunities in the passing game.
• Keep an eye on the pro transition of rookie wide receiver Alshon Jeffery. He has talent, but rookies can struggle early to beat press-coverage, separate on the deep ball and run clean routes.
• Marshall and cornerback Charles Tillman are the featured act to watch during one-on-ones. Even Thursday, with Tillman playing from an off-man position, was quality work between two veterans.
When the pads go on this weekend, expect both players to compete hard at the line of scrimmage. That's good football.
