You nailed it, the problem is basically WASTING the low cap hit years of drafting a 1st round QB. It is why it is such a luxury to have that QB under a 5 year deal and maximize 4-5 years of that limited window to pay elsewhere to build a complete team. Yes there will still be a low cap hit window in what, years 3-5, but this means Love sat for 2 years and who knows how he'll pan out when he gets to play. You basically said it yourself though, it is silly grooming a QB for a few years when so many QBs can play in year 1 and play well. Mahomes is a year 2 guy but still going past 2 would just be silly.
