Forward isn't a bad thing if the midfield is still driving it forward and he has chances to score, unless it's a "I'm an idiot coach that thinks he's an elite forward" 80/20 forward time splits like Teague was doing at times.
Ultimately I think a bigger pie is better for the Blues midfield, they were blown off the park in that area last year. Dogs are a good example that a huge pie is possible with a strong and deep midfield, not that they're on that level of course and they're the anomaly for sure, but Cripps is the top dog, Walsh is the other and the rest filter in below that.
Looking at LY...
ADE: 116, 103, 97 and 96
BRI: 118, 110, 100 and 100.
CAR: 117, 86, 84 and 81
ESS: 115, 114, 93 and 87
FRE: 107, 100, 100 and 90
GWS: 107, 97, 97 and 93
GEE: 113, 104, 101 and 99.
GC: 125, 101, 90 and 90
MEL: 124, 111, 87 and 83 (Ruck at 120 though)
PA: 113, 106, 93 and 87
STK: 126, 93, 92 and 90
SYD: 112, 109, 93 and 77 (you can see why Heeney should play mid
WBD: 129, 120, 103 and 103.
Basically if you're in a good side, with a good midfield, the majority have 2 guys go big and 2 guys in the solid 90s, most of those top teams had a 5th guy right about as well. Melbourne actually a weird exception albeit Gawn distorts reality there.
You'll also notice a distinct lack of the bottom sides for the most part here.
Realistically if they're all fit I think Walsh might now be their top dog but that leaves Cripps to get to that 110-115 range still while still leaving room for Cerra, Hewett and Kennedy to get their fill. Walsh may take a while to get back as well, he's never dealt with an injury before after all.
Ultimately, think the points are there if the team can take them as a whole, a big part of the positives for me is that their whole pie should be a lot bigger.
Bust factor is very high, the real part of picking Cripps is having the contingency in place. What do you do if he's a clear bust at r3, what's the plan if he's just mediocre mid 90s? What about 105? I took him last year when he was a much worse proposition but he was out of my side by round 3 for the cost of a trade. It's why getting one or two of this type of pick is manageable but filling your side with them isn't! (He says with a side full of them!)
