I get the allure of this strategy, I’ve had a couple different top tier TE’s drop to me in the first 4-6 rounds of a few different drafts. the few times I’ve tried doing it and actually playing it out in a league, I’ve always been disappointed by the end of the season.
Jared has the best answer on why this will probably work out the same for you, his stats are hella instructive. But there’s another downside to this that I don’t think people always consider. When you follow this strategy, you have basically taken your flex spot and turned it into a 2nd TE spot. Sure, you don’t have to play both of your high draft capital guys every week, but most years, you’re going to have to if you want to withstand victories all year long. If you luck out and get mid round RBs and WRs who become more valuable than you’re 2nd TE, that’s awesome, but then you’re left with a really expensive backup to what is arguably the least important skill position in fantasy taking up room on your bench. If one of your mid round guys doesn’t step up, you’re team is locked into a certain style of lineup almost every week, essentially a no flex one. That makes it hard to work the matchups from week to week.
