that is certainly an easy situation to find oneself in.... It is not uncommon to spend a lot of cash on one player when in a battle. it really comes down to how much each party is willing to spend. that said, a player like Mr. Wright will certainly help your team immediately - especially since he has the correct IQ to match your offense and defense.... and I see that almost all the upper-classmen you signed are like that. this should help your team a lot this year (although I didn't look at your returning players to see how good your overall team will be).
really it all comes down to what you are trying to accomplish - do you want to be good this year? then maybe you should grab a bunch of jucos and transfers if you able. Or are you trying to build a 'dynasty' and be good every year? then you need to balance your classes out.... eventually you can do both - be good every year and have mostly balanced classes.
way back in the day, I was told a good coach can go to the NT every year. I agree with this. It's probably harder though if you are top heavy and a less experienced coach though since you can't make many recruiting gaffs and win with a bunch of freshmen and sophomores.
whatever you decide, this is still a learning year. you have 6 seniors leaving after this season too, so you can re-set a little bit and learn from your experiences.
like real life, it seems that most coaches who win the national title do so with 4 year players. sometimes they bring in a player or two to compliment things, but it probably just depends on their need and availability. there are some coaches that do well with more jucos and transfers too but I think it's a little more difficult given the IQ issue.
