Bertans can always be signed with a minimum deal. But anything more requires cap space or an exception. There's no reason to think LLE (alternative acronym for the bi-annual exception) for him, as his stock isn't all that high after two major injuries. The min would be enough to get him on a two-year deal, and maybe it would let him get a three-year deal if they guarantee the first two years or something like that. Finally, Manu was signed with the room exception last year, not the LLE. The difference between the two is that the room exception is what teams have when they use cap space, while the LLE is a cap exception like the MLE. So just like the MLE, the Spurs didn't have the LLE last year. Other main difference is that the room exception is like twice as large as the LLE.
