I've been watching Bomar on the NFL channel vs. the Patriots. Midway through the third quarter he's 6 for 12 for 73 yards and 3 points. It's possible he's having an off night, but based on these stats, I'd be hard-pressed to call him an upgrade.
He also appears to throw sidearm. In a world of 6'5" behemoths on the defensive line, I'd be concerned about that if I were his coach. As for trading for him? No way would I give up a warm body or a draft choice. If he's available in the off-season, it might be worth taking a flyer on the guy, signing him for the minimum and seeing what he does in training camp.
