This being the same Crouch who was AA in 2017, broke the record for most disposals in that year and won his club's B&F? You were just as cold on Brodie when I mentioned him last year, sometimes the handlers don't know how to manage the thoroughbreds, the formula for Brodie was put on display this year & has made the GC look a tad bit silly.
For a player who is still only 27, has battled persistent groin injuries & will be as a cheap as they come, he's value & could fulfill the role Taranto plays, quite comfortably. They are actually pretty similar when it comes to hurt factor with the disposals, Crouch has always been a high accumulator, his defensive side is fine, he's a 5 tackle a game player at his best, often hitting double figures. his clearance work also very good. But the most important aspect is he will come virtually free so if he's a bust we can move on and make a play for a genuine A list footballer (I just don't see it with Taranto).
As for the ruck debate, depth in this area is critical, 2 A graders are better than one, I think you have overlooked the fact that Melbourne are the reigning premiers who also happen to have the best ruck in the comp, a club captain as well. Grundy is the only guy who can consistently match it with Gawn, it makes perfect sense that the 2 clubs with the best lists are chasing him. Don't forget we are playing catch-up at this point & will continue to do so over the next few years.
I'd have no problem having two top tier rucks in that age group on similar dosh, you probably extend the life of both all things considered. If Nank goes down we're in trouble in this area, that's just my take on the situation, others may disagree but Soldo & co. aren't good enough to match it with the best.
