He's improved and seems to be a great depth piece, but Whit is a hall of famer and still performing at a high level. Why would you kick him to the curb? Maybe they should work Boom as a guard more - Edwards has been up and down and maybe he's hit his ceiling.
Still think we should pay Boom to keep him, but since he's a backup without a ton of tape, I don't imagine he'll be a super high priced, in demand free agent.
The Iowa rookie looked good at LT in pre-seaon too. So they seem to have good depth at one of the most important positions in football - heard many analysts say - the 3 most important positions are LT, Edge Rusher and QB.
