A few thoughts that come to mind:
Clements has been inconsistent this season. He doesn't look comfortable out there. Is he hurt? Is his mind right? I'm not sure, but this situation strikes me as a little odd. As much as the 49ers like Brown, teams facing Peyton Manning and the Colts need all the experience they can get at cornerback.
Clements will still play in the game, presumably. Might his playing time come at Dre Bly's expense in various nickel situations?
Clements is 29 years old and has started 128 games since 2001. His salary jumps to $6 million in 2010 and his contract becomes prohibitive in 2011 and beyond. Those things wouldn't affect Clements' status for a game in Week 8 this season.
I'd be surprised if this were part of some broader transition from cornerback to safety. Several 49ers fans have asked me about this. Coach Mike Singletary laughed when a reporter brought it up a couple weeks ago. I think Clements would be a few years away from that sort of move.
This one is a bit baffling from this angle and I don't have enough information to say anything definitive. Yes, Clements has been inconsistent, but he's still a good talent and a hard worker and a good teammate, by all accounts. We haven't seen the last of him as a starting corner in the NFL.
