Travel arrangements are actually pretty good. Chartered flights out of town, and the team is usually at a top rate hotel fairly close by wherever they're playing. Nutrition? Sadly lacking when compared with other programs. For instance, Florida has an entire staff solely dedicated to the nutritional care of players. Player housing is another short-coming. Overall COA allowance is rather small, too. There are actually several G5 teams that far exceed what SU pays out in COA. SU's field house is pretty good, on par with a number of teams but, it doesn't touch any of the powerhouse P5 programs (e.g. Florida), and a few of the G5s (e.g. Cincinnati) have better facilities, too.
As to how these shortcomings (real or perceived) might impact how successful SU is/becomes, it probably does to a degree. Nice "digs" are always going to have an influence on the marquee recruits. Personally, if I were a player, I'd have chosen Florida, if my only concern was to play for a team that had all the bling. For right now, the biggest advantage that the current staff has over many other programs is that they're very personable, and have a genuine concern about the kids they're recruiting. Long term, though, SU is going to have to cough up the dough to help them out.
