The binary question is too simplistic in my opinion. I think a sliding scale from 1-5 between the two extremes would have been better. With the scale being 1: All Players Fault to 5: All Red Autry's Fault, I think I'd put my answer at 2.
A major criticism of Red in this thread had been roster construction. Look at the roster to start the season:
5: McLeod, Hima
4-5: Brown, Carey
4: Williams
3-4: Taylor
3: Bell
2-3: Westry, Copeland
2: Cuffe
1-2: Mintz, Starling
With Patterson locked into a redshirt because of the depth of guys in front of him.
The injuries to McLeod and Hima perhaps should have been anticipated, but season or career ending injuries just can't really be accounted for... To the extent that they can be, Red had really good big man depth. To start the season there were six players who can man those two positions, with four players that can play the 4, and four that could play the 5. Included in those players were McLeod, a very high upside transfer (at least defensively), Brown (our best player this year) and Williams (our highest potential player, whom had very high expectations). Those guys would have had Carey, Taylor and Hima to give them a break... But ultimately, if each of those three players had reached their 75% of expectation, they'd have taken all the minutes because taking them out in a close game world have been stupid. So they'd have each averaged 28 minutes a game.
Injuries and poor behavior decimated the best three big men, with only Brown still around. Taylor wasn't expected to be a starter alongside Bell, he was supposed to be the backup at the 3 and the 4. Williams getting suspended pushed him into a role he wasn't supposed to be playing. Hima and Carey are about what we'd expect, limited physically and not ready for prime time respectively.
So that brings us to the other forward spot. Bell is arguably our best 3pt shooter coming into the season (although people seem to forget Williams shot a higher percentage), and had physical potential second only to Williams. He want going to be beaten out unless Westry was top of his game to start the season. The plan was Bell, with Westry, Taylor and Copeland pushing him for minutes.
Westry being injured and Taylor being forced to the 4 has given Copeland the opening he needed, but we wanted him to be playing limited forward minutes, not become a few facto starter.
Copeland, Westry and Cuffe should have been fine backing up Mintz and Starling, but again, injuries pushed guys into different positions or onto the bench.
What we've seen the last few games is the result of us playing severely undersized, with a 4 playing center, a guy recruited to be a 2-3 playing PF, and a guy recruited to be a 1-2 playing small forward.
We're getting crushed in rebounding, but are still in games despite enormous size deficiencies.
A responsible and effective Williams would have made this team so much better, and his loss due to his choices can't be blamed on Red. JB didn't do much better dealing with Williams...
That problem was compounded by our only two available centers being hurt.
Imagine a lineup with a healthy McLeod, Brown, a Williams that reached expectations, Starling and Mintz.
That team is so much better than what we have now.
