Malik Watson has allowed 6 Seimian sacks in 2 games. Broncos have the 2 worst rated RTs in the NFL. And few decent OTs are available to trade for. That is why it is common knowledge that teams need to draft OTs in the 1st round. 4+ year veteran OTs are extremely expensive against a salary cap. Picking them in the 1st round shoould give you quality and salary protection for  a few years. Good ones with talent and size are rare and the best place to get them is very early in the draft. One of the best sackers in NFL, Von, has gotten 2 sacks in 6 games. Worst rated starting tackle in NFL, Watson, has allowed 6 sacks in 2 games. Why spend $20 million on Von who gets 16 sacks per year when one OT is allowing sacks at a rate of 32 per regular season.... making $5 million a year?
