Who's blocking Turgut's progression?

Only himself

Jordan Lane

Looks like it to me. No offence to Turgut, I like him, but our first pick back rowers are Manu, Mini and Hadley, deservedly so. After that we're into Washy, who has utility value at hooker and loads of experience, and Lane has been given his chance by Radford and leapfrogged Turgut IMO. If he were to play at centre he has Griffin, Connor, Tuimavave and Logan ahead of him, again IMO. I'm not sure who this raft of progression-blockers are.

So you've just agreed with Lane being 1 of them and then named the rest.
So in effect have you not answered your own question?
Yes that could all change next season with departures and arrivals.
For me Turgut hasn't shown enough to be anyway near the starting 17 yet anyway, headless chicken trying too hard springs to mind.
So not sure he is actually being blocked as alluded too but merely not taken his chance unlike Fash and Lane.

has he not taken a chance, or just not good enough for an aspiring SL side?

Not at all. The assertion was that Turgut's progression is being blocked by inadequate senior players. I agree that Lane, as a junior player promoted by Radford, is now ahead of Turgut in the pecking order.

In my opinion both.
had high hopes for Turgut but when given a chance he has done nothing to show he has the ability to be a super League player.
he is out of contract at the end of the season so i think Radford will send him out on loan/DR when we have some bodies back and his is fit and depending on how well he does will determine whether he gets an extension.
On current form Championship player at best

You're so limited you can't even grasp the fact I'm defending Pearson re marquee signings with respect to the risk factor.

Washbrook is blocking several players from getting valuable experience whilst not offering enough to justify his place 'IN MY OPINION', he's a tryer but he isn't cutting the mustard.
People say he's reliable, at giving effort yes, he misses plenty of tackles and more often than not third man in, he's slow at dummy half, he rarely ever bends the line because he lacks pace, I mentioned his error count previously, I haven't bothered to check what that's like since.
He's certainly been picked over Litten countless times and very probably Turgut who was utilised in the forwards and at centre last season, he (Turgut) will not progress any further until he gets more game time. If Radford doesn't get him game time he will fall away and be another youth set up failure that the club failed to exploit, given he was the England academy captain and was touted as the next big thing and that he's only just turned 22 I'd say the club need to give him a chance, don't you?

Clearly you are of limited thinking capacity because so eager were you to start an argument as the good little troll that you are, you missed that I defended Pearson not signing marquee players, you then threw a nonsensical statement into the equation asking me where my money was, as if that had anything to do with the subject at hand re marquee signings or otherwise, just clutching at some little straw.
Then you've done nothing but try to avoid the fact that you were wrong and wouldn't enter into the debate about recruitment and/or marquee signings. I simply said there was nothing stopping Pearson from signing a marquee player but the consideration was the financial risk.
All you could muster with your limited capacity was to start bitching in your usual fashion, it's just rinse and repeat, as I said, you clearly are of limited capacity and it's you whom are the troll with your incessant argumentative nature and yet another jibe saying I'm not a supporter, aw bless yah

You said senior players. Washbrook is one. Who are the others?

Christ on a bike, you can hardly say Radford:
a) Hasn't given Turgut an opportunity. He's played almost 30 games, right?
b) Isn't giving youth a chance. Fash, Masi, Lane, Downs, Turgut, Litten..how many appearances have they clocked up over last season and this? It's not a handful, it's a lot.

Lane's overtaken him in the pecking order from what I can see, that happens. Not everyone will make it. Look at Ben Crooks for example. Darryl Powell shipped him on and he's playing in the championship. Radford's judgement proved right again.
