Episode 1 showed some promise, kinda, but episode 2 was just meh all around. No titties to speak of, which should be an every ep type of thing. Entourage's great appeal was that it was funny, and it showcased tons of hot 23yr old mattresses (Model/actresses) getting naked. So far this show is lacking in funny, and if you were to start slacking on the amount of mattress titties being shown, well, that just tears it.
The other issue with this show, is it's hard to show the perspective of an athlete, since there's always a looming deadline on the money coming in from multi-million dollar paychecks. It may be 5 years, or 10 years, or maybe even 15, but it's inevitably over as soon as your body can no longer handle it. This fact casts a pall over this perspective that Entourage didn't have. The tone there was much more free-spirited. In the world of hollywood, you can theoretically reinvent yourself every few years and continue to make big time bucks, so this adds to an atmosphere of "anything's possible if I can just do X to get back on top/get that next role/get that next paycheck!"
That leaves you to show the perspective of the agents (Rock and Corddry), which is probably a tougher sell for the audience to sympathize with, since as one dirtbag on this show said already, "Deep down you're just a hustler like all the rest".
