I've seen him play a few times (Gardner), and, with all due respect BP, don't think he'd be good enough to play for us. He's got an eye for a pass and can hit a ball but often tries to do a bit too much with it for my liking and wastes possession when he could have given a simpler pass. Admittedly he works very hard for the team but I think he lacks a little bit of quality to step up into our league and perform consistently well from what I've seen.
Lee Gregory on the other hand would be a terrific signing - great off the ball movement (something I think we lack in our forwards and in our attacks in general), quick, can dribble well and, above all, knows where the goal is.
