Iaquinta would be ideal, I feel he's the right guy to test him now coming in, of course the UFC won't be able to cash in on that. I think he's being gifted a top 5 in the toughest division in MMA with no W's in the UFC
As far as others besides Iaquinta, I think Lee and Gillespie are way too risky for the UFC if Chandler comes in with 2 L's to start they basically hyped a guy whos gonna struggle to remain in the top 20. Bobby Green would be the safe bet if they reallly want to feed Chandler a W with a notable opponent in his 2nd match
