Definitely bring him in, all the better if he's not taking up a DP spot. Terry is still on top of his game, having played every minute of the season last year (which was probably not a good thing; Mourinho's great flaw is his unwillingness to use his squad). And he has rebounded from a shaky start to the current season to earn comments from Roy Hodgson acknowledging that he would like to be have been able to call Terry up for the England squad at the Euros. If Terry could have played at this year's Euros, he can certainly play in MLS.
