You just have to look at his contract to know the Rams weren't going to keep him next year. That's why I've been saying all along that Noteboom is their LT going forward. They are making a mistake by not extending him now. Why wait and give his agent leverage at the end of the season. Extending him now will be cheaper than after the season.
They should release Havenstein and say goodbye to his matador blocks and play Noteboom this year at RT. He's a far better pass blocker than Rob and would protect Stafford a lot better. It would also clear about $5M in cap getting them under the cap with a couple of million to spare.
It would also make sense to play Shelton at center, Evans at RG, and Corbett at LG. This would allow them to use Edwards as their swing OT to take over RT next year. After that, they have Alaric Jackson to play swing OT. Jackson has talent he's just painfully raw and needs a redshirt year on the PS. They also have Brewer to play swing OT if they want to keep Edwards at OG.
