hope widnes manage to stay up there as they were exciting to watch last night, but i do remember a copule of seasons' ago they fell away badly after a good start, clinging on to top 8

Both. The players are the ones that go out there and produce shockers like that. Not a lot Radford can do in the 80 minutes.

But Radford picks these players, picks the tactics. He and the coaching staff train these guys all week and something is not working.

Plenty of blame to go around IMO.

80% coach, 20% Players.
The coach chooses which players we accquire, which players play. The coach drills the players, the coach instills the mental fortitude, the coach bonds the players to want to play for the badge and each other. The coach identifies the lack of skills/deficiencies and builds/develops players or uses his team to address such. The coach looks at the opposition and what they do, what are their strengths and weaknesses and pulls that apart to make a game plan.
The coach adjusts what's going on live, the coach decides when the interchanges happen, when a.player needs subbing earlier.
The players are tools, they all have talent, there is not a vast difference in ability for any given position, maybe 5-10% max within SL
What makes more difference is how the players are gelled together, how they are mentally prepared and coached in playing rugby to the best of their ability for 80 minutes. The coach that does that the best and with a bit of luck invariably has a winning team.

Don't care who the coach is. Basic skills of tackling was not apparent last night.Stood still and passing the ball is not something a professional rugby player should be doing. Yes Radford takes the brunt put the players should take a look in the mirror as well
